Introduction
The somatomedins, or insulin-like growth factors (IGFs), comprise a family of peptides that takes part in mammalian growth and development. IGF1 mediates various growth-promoting effects of growth hormone (GH; MIM 139250). Early studies showed that growth hormone did not directly stimulate the incorporation of sulfate into cartilage, but rather acted through a serum factor, termed 'sulfation factor,' which later became known as 'somatomedin' (Daughaday et al., 1972). 3 main somatomedins have been characterized: somatomedin C (IGF1), somatomedin A (IGF2; MIM 147470), and somatomedin B (MIM 193190) (Rotwein, 1986; Rosenfeld, 2003).

Introduction
GMCSF is a cytokine that controls the production, differentiation, and function of granulocytes and macrophages. The active form of the protein is found extracellularly as a homodimer. This gene has been localized to a cluster of related genes at chromosome region 5q31, which is known to be associated with interstitial deletions in the 5q- syndrome and acute myelogenous leukemia. Other genes in the cluster include those encoding interleukins 4, 5, and 13.
GM-CSF stimulates the growth and differentiation of hematopoietic precursor cells from various lineages, including granulocytes, macrophages, eosinophils and erythrocytes.

Background
Recombinant Granulocyte-Macrophage Colony-Stimulating Factor (GMCSF) is a protein that plays a crucial role in the production and differentiation of white blood cells, including granulocytes and macrophages. It is a potent stimulator of hematopoietic stem cells, which are responsible for the production of all blood cells in the body. Recombinant GMCSF is a synthetic version of the protein that is produced using recombinant DNA technology.
Recombinant GMCSF has been extensively studied for its potential therapeutic applications in a variety of medical conditions, including cancer, autoimmune diseases, and infectious diseases. In cancer, GMCSF is used as an immunostimulatory agent to enhance the immune response against cancer cells. By stimulating the production and differentiation of white blood cells, GM-CSF can increase the number of immune cells that can recognize and attack cancer cells. This approach has been successfully used in the treatment of several types of cancer, including melanoma and leukemia.
In autoimmune diseases, recombinant GMCSF has been investigated as a potential treatment for conditions such as rheumatoid arthritis and multiple sclerosis. These diseases are characterized by an overactive immune response that attacks healthy tissues in the body. By modulating the immune response, GMCSF may be able to reduce inflammation and prevent further damage to affected tissues.
In infectious diseases, recombinant GMCSF has been studied as a potential treatment for conditions such as sepsis and HIV/AIDS. In sepsis, a severe bacterial infection, GMCSF may be able to stimulate the production of white blood cells and improve the immune response against the infection. In HIV/AIDS, GMCSF may be able to enhance the immune response against the virus and reduce the risk of opportunistic infections.
Recombinant GMCSF is typically administered by injection, either directly into the affected tissue or into the bloodstream. It is generally well-tolerated, although some patients may experience side effects such as fever, fatigue, and muscle pain.
In conclusion, recombinant GMCSF is a promising therapeutic agent with potential applications in a variety of medical conditions. Its ability to stimulate the production and differentiation of white blood cells makes it a valuable tool in the treatment of cancer, autoimmune diseases, and infectious diseases. Ongoing research is likely to uncover new uses for this protein and further refine its therapeutic potential.

Introduction
VEGF-C, also known as Vascular Endothelial Growth Factor Related Protein (VRP), is a recently discovered VEGF growth factor family member that is most closely related to VEGF-D. Human VEGF-C cDNA encodes a pre-pro-protein of 416 amino acids residues. It is almost identical to the mouse VEGF-C protein. Similar to VEGF-D, VEGF-C has a VEGF homology domain spanning the middle third of the precursor molecule and long N- and C-terminal extensions. In adults, VEGF-C is highly expressed in heart, placenta, ovary and small intestine. Recombinant human VEGF-C, lacking the N- and C-terminal extensions and containing only the middle VEGF homology domain, forms primarily non-covalently linked dimers. This protein is a ligand for both VEGFR-2/KDR and VEGFR-3/FLT-4. Since VEGFR-3 is strongly expressed in lymphatic endothelial cells, it has been postulated that VEGF-C is involved in the regulation of the growth and/or differentiation of lymphatic endothelium. Although recombinant human VEGF-C is also a mitogen for vascular endothelial cells, it is much less potent than VEGF-A.

Introduction
Vascular endothelial growth factoris an important signaling proteininvolved in both vasculogenesisand angiogenesis. As its name implies, VEGF activity has been mostly studied on cells of the vascular endothelium, although it does have effects on a number of other cell types (e.g. stimulation monocyte/macrophagemigration, neurons, cancer cells, kidney epithelial cells ).VEGF mediates increased vascular permeability, induces angiogenesis, vasculogenesis and endothelial cell growth, promotes cell migration, and inhibits apoptosis. In vitro, VEGF has been shown to stimulate endothelial cell mitogenesisand cell migration. VEGF is also a vasodilator and increases microvascular permeability and was originally referred to as vascular permeability factor.
Elevated levels of this protein is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy.

Background
GHBP is a transmembrane receptor for growth hormone. Binding of growth hormone to the receptor leads to receptor dimerization and the activation of an intra- and intercellular signal transduction pathway leading to growth. A common alternate allele of this gene, called GHRd3, lacks exon 3 and has been well-characterized. Mutations in GHBP have been associated with Laron syndrome, also known as the growth hormone insensitivity syndrome (GHIS), a disorder characterized by short height.

Introduction
Pleiotrophin (Osteoblast-Specific Factor-1, OSF-1) contains 136 amino acid residues. The sequence is very rich in cationic amino acids (24% of the residues); lysine cluster sequences are found in the N-terminal and C-terminal ends of the structure.
The OSF-1 gene was shown by Northern blotting analysis to be expressed in mouse calvarial osteoblast-enriched cells and in mouse brain tissues, but not in thymus, spleen, kidney, liver, lung, testis or heart. Pleiotrophin has the ability to promote adhesion, migration, expansion, and differentiation of human osteoprogenitor cells. In addition to certain types of cancer, the embryonic growth and differentiation factor pleiotrophin is found also in adults in inflammatory diseases. In osteoarthritis, pleiotrophin is especially expressed in early stages, and its concentrations in the synovial fluid could serve as a marker for the progress of the disease. Pleitrophin might be involved in cartilage repair in osteoarthritis, in particular, in earlier stages.

Introduction
The somatomedins, IGFs, comprise a family of peptides that play important roles in mammalian growth and development. IGF1 mediates many of the growth-promoting effects of GH. Early studies showed that GH did not directly stimulate the incorporation of sulfate into cartilage, but rather acted through a serum factor, termed 'sulfation factor,' which later became known as 'somatomedin. Three main somatomedins have been characterized: somatomedin C (IGF1), somatomedin A (IGF2; MIM 147470), and somatomedin B.

Background
IGF stands for INS like growth factors, which are proteins that have a high similarity to INS. They are part of a complicated process that uses cells to communication with the physiologic environment around them. IGF’s complex system is often called the ‘axis’. This consists of:
● Two cell-surface receptors (IGF1R and IGF2R)
● Two ligands (IGF-1 and IGF-2)
● A family of six high-affinity IGF-binding proteins.
● Proteases.
The Effect IGF Has On The Body
Many unique tissue types express the IGF-1 receptor, and the effects can vary. It induces the survival of neurons, may catalyse skeletal muscle hypertrophy by inducing protein synthesis, and by blocking muscle atrophy. It works as a protector for cartilage cells, and may work to be an anabolic factor for the bones. When used in high concentrations, it can activate the INS receptor, and can even complement the effects that INS has on the body.
Diseases And IGF
Diseases and IGF are closely related, and a number of them can be affected. The INS IGF axis is thought to have an effect on aging, with an increased life span shown in fruit flies when used in studies.
It is also important to note the crucial role that IGF plays in cancer and diabetes - IGF- 1 has been shown to stimulate growth in both prostate and breast cancer cells. The degree of risk that IGF-1 poses is up for debate, and many scientists are not in agreement. IGF has also shown to have the ability to decrease blood glucose levels, although not quite as effective as INS.
How Was IGF Discovered?
Investigators began studying the effects of biological substances on cells and tissues outside the body when IGFs were discovered. The name is self explanatory in the fact that IGF performs INS actions in some tissues, but is less potent than INS at decreasing blood sugar. Its fundamental action is to stimulate growth, whether that be within the epidermal growth factor or the nerve growth factor.
What’s The Difference Between IGF-1 And IGF-2?
The two types of IGF are IGF-1 and IGF-2. Although the names are similar, the specific actions that they take are different - they bind and activate completely difference receptors. The major actor in them both is the effect that they have on cell growth. Most of the actions of the pituitary GH are mediated by IGFs, but predominantly IGF-1. GH works to stimulate many tissues within the body, especially the liver which then secretes IGF-1. This then causes hypertrophy, or in layman's terms, an increase in cell size, as well as hyperplasia which is an increase in the number of cells.
The IGF-1 concentration will increase during childhood and hit peak during puberty, but will then decrease afterwards, as does the hormone secretion itself. It has been proven that children and adults with a deficiency of the GH have low serum IGF-1 concentrations when put in comparison with others in the same age range. Patients who have conditions like acromegaly have been shown to have increased serum IGF-1 concentrations. The production of IGF-2 is less dependent on the secretion of GH than IGF-1, and is much less important for stimulating linear growth.

More Info

Introduction
KGF is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. FGF7 is a potent epithelial cell-specific growth factor, whose mitogenic activity is predominantly exhibited in keratinocytes but not in fibroblasts and endothelial cells. Studies of mouse and rat homologs of this gene implicated roles in morphogenesis of epithelium, reepithelialization of wounds, hair development and early lung organogenesis.

Background
FGF stands for fibroblast growth factor that have proteins encoded inside them. The FGF family possess broad mitogenetic activities and are involved in a lot of processes in the body. Some of the biological processes that they are included in are embryonic development, cell growth, tumor growth and tissue repair. FGF-7 is often also commonly referred to as keratinocyte growth factor or KGF and studies have focused on the link between the protein and certain tumor growth.
Structure
Studies have found that the crystal structure of FGF7 is comparatively similar to that of FGF10. For instance, FGF7 does interact with D2, linker as well as D3 of the receptor. Similar to other FGFs much of interaction to do with D2 is confined to conserved residues as well as the residue Arg 251 in the linker domain and the hydrophobic surface of D2. That said there are notable differences and some models predict that FGF7 actually interacts with three loops in D3.
Mechanism
A member of the FGF family, this factor acts completely exclusively through a subset of FGF receptor isoforms. These are mainly expressed by epithelial cells. Indeed, studies suggest that the factor specifically acts on epithelial cells. This in turn causes increased proliferation differentiation and migrations of the aforementioned cells.
Interactions
FGF7 and FGF10 can interact with one of the FGF receptors that is expressed by the epithelial cells. As such, it could be the case that this interaction could cause a protective factor for these epithelial tissues. The protein has also been shown to interact with Perlecan. Also referred to as basement membrane specific heparan sulfate proteoglycan core protein, this is encoded by the HSPG2 gene. A large multi domain this cross-links and binds to various extracellular matrix components as well as self surface molecules. Since FGF7 binds specifically with the perlecan protein, research suggests that i should be considered a novel biological ligand for FGF-7. This could mean that interaction has an influence on both tissue remodeling and cancer growth.
Function
Studies have shown that FGF-7 expression is completely unregulated during minor or even chronic injury. This has lead researchers to believe that the protein is used to heal or repair epithelial cells. Furthermore, FGF-1 also triggers the formation of apical ectodermal ridge throughout the development of limbs in the body.
Recently, it has seemed to be the case that FGF-7 has been linked to skin injury repair, and has also been found to play some sort of role in breast cancer. As well as this, it is a vital regulator of HPC’s. It is vital because it can induce de novo activation of these HPCs.
Further research has shown that FGF6 is a niche signal that is required for the stimulation of adult liver progenitor cells and this can support liver regeneration. This research has lead to the suggestion that FGF7 could be a possibility therapeutic target for those suffering from liver diseases.
Studies like this are just one of the reasons why researchers continue to explore fgf-7, it’s functions and interactions.
Protein content
Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280 nm using the absorbency value of 0.9 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a calibrated solution of KGF as a Reference Standard.

More Info

Introduction
Fibroblast growth factors (FGFs) comprise a family of at least eighteen structurally related proteins that are involved in a multitude of physiological and pathological cellular processes, including cell growth, differentiation, angiogenesis, wound healing and tumorgenesis. The biological activities of the FGFs are mediated by a family of type I transmembrane tyrosine kinases which undergo dimerization and autophosphorylation after ligand binding. Four distinct genes encoding closely related FGF receptors, FGF R1 - 4, are known. All four genes for FGF Rs encode proteins with an N-terminal signal peptide, three immunoglobulin (Ig)-like domains, an acid-box region containing a run of acidic residues between the IgI and IgII domains, a transmembrane domain and the split tyrosine-kinase domain. Multiple forms of FGF R1 - 3 are generated by alternative splicing of the mRNAs. A frequent splicing event involving FGF R1 and 2 results in receptors containing all three Ig domains, referred to as the a isoform, or only IgII and IgIII, referred to as the b isoform. Only the a isoform has been identified for FGF R3 and FGF R4. Additional splicing events for FGF R1 - 3, involving the C-terminal half of the IgIII domain encoded by two mutually exclusive alternative exons, generate FGF receptors with alternative IgIII domains (IIIb and IIIc). A IIIa isoform which is a secreted FGF binding protein containing only the N-terminal half of the IgIII domain plus some intron sequences has also been reported for FGF R1. Mutations in FGF R1 - 3 have been found in patients with birth defects involving craniosynostosis. The complex patterns of expression of these receptors as well as the specificity of their interactions with the various FGF ligand family members are under investigation.

Introduction
Vascular endothelial growth factoris an important signaling proteininvolved in both vasculogenesisand angiogenesis. As its name implies, VEGF activity has been mostly studied on cells of the vascular endothelium, although it does have effects on a number of other cell types (e.g. stimulation monocyte/macrophagemigration, neurons, cancer cells, kidney epithelial cells ).VEGF mediates increased vascular permeability, induces angiogenesis, vasculogenesis and endothelial cell growth, promotes cell migration, and inhibits apoptosis. In vitro, VEGF has been shown to stimulate endothelial cell mitogenesisand cell migration. VEGF is also a vasodilator and increases microvascular permeability and was originally referred to as vascular permeability factor.
Elevated levels of this protein is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy.

Introduction
The secreted polypeptide noggin, encoded by the NOG gene, binds and inactivates members of the transforming growth factor-beta (TGF-beta) superfamily signaling proteins, such as bone morphogenetic protein-4 (BMP4). By diffusing through extracellular matrices more efficiently than members of the TGF-beta superfamily, noggin may have a principal role in creating morphogenic gradients. Noggin appears to have pleiotropic effect, both early in development as well as in later stages. It was originally isolated from Xenopus based on its ability to restore normal dorsal-ventral body axis in embryos that had been artificially ventralized by UV treatment. The results of the mouse knockout of noggin suggest that it is involved in numerous developmental processes, such as neural tube fusion and joint formation. Recently, several dominant human NOG mutations in unrelated families with proximal symphalangism (SYM1) and multiple synostoses syndrome (SYNS1) were identified; both SYM1 and SYNS1 have multiple joint fusion as their principal feature, and map to the same region (17q22) as NOG. All NOG mutations altered evolutionarily conserved amino acid residues. The amino acid sequence of human noggin is highly homologous to that of Xenopus, rat and mouse.

Introduction
Stem cell factor / KIT ligand (SCF) is a cytokine which binds CD117(c-Kit). SCF is also known as "steel factor" or "c-kit ligand". SCF exists in two forms, cell surface bound SCF and soluble (or free) SCF. Soluble SCF is produced by the cleavage of surface bound SCF by metalloproteases. SCF is a growth factor important for the survival, proliferation, and differentiation of hematopoietic stem cells and other hematopoietic progenitor cells. One of its roles is to change the BFU-E (burst-forming unit-erythroid) cells, which are the earliest erythrocyte precursors in the erythrocytic series, into the CFU-E (colony-forming unit-erythroid).

More Info

Introduction
VEGF-C, also known as Vascular Endothelial Growth Factor Related Protein (VRP), is a recently discovered VEGF growth factor family member that is most closely related to VEGF-D. Human VEGF-C cDNA encodes a pre-pro-protein of 416 amino acids residues. It is almost identical to the mouse VEGF-C protein. Similar to VEGF-D, VEGF-C has a VEGF homology domain spanning the middle third of the precursor molecule and long N- and C-terminal extensions. In adults, VEGF-C is highly expressed in heart, placenta, ovary and small intestine. Recombinant human VEGF-C, lacking the N- and C-terminal extensions and containing only the middle VEGF homology domain, forms primarily non-covalently linked dimers. This protein is a ligand for both VEGFR-2/KDR and VEGFR-3/FLT-4. Since VEGFR-3 is strongly expressed in lymphatic endothelial cells, it has been postulated that VEGF-C is involved in the regulation of the growth and/or differentiation of lymphatic endothelium. Although recombinant human VEGF-C is also a mitogen for vascular endothelial cells, it is much less potent than VEGF-A.

Introduction
Epidermal growth factor has a profound effect on the differentiation of specific cells in vivo and is a potent mitogenic factor for a variety of cultured cells of both ectodermal and mesodermal origin. The EGF precursor is believed to exist as a membrane-bound molecule which is proteolytically cleaved to generate the 53-amino acid peptide hormone that stimulates cells to divide. EGF stimulates the growth of various epidermal and epithelial tissues in vivo and in vitro and of some fibroblasts in cell culture. Long EGF is a recombinant analog of Human EGF developed as a replacement for use in therapeutic cell culture applications as a like-for-like supplement for Recombinant Human or native EGF.

Introduction
Vascular endothelial growth factor is an important signaling protein involved in both vasculogenesis and angiogenesis. As its name implies, VEGF activity has been mostly studied on cells of the vascular endothelium, although it does have effects on a number of other cell types (e.g. stimulation monocyte/macrophage migration, neurons, cancer cells, kidney epithelial cells ).VEGF mediates increased vascular permeability, induces angiogenesis, vasculogenesis and endothelial cell growth, promotes cell migration, and inhibits apoptosis. In vitro, VEGF has been shown to stimulate endothelial cell mitogenesis and cell migration. VEGF is also a vasodilator and increases microvascular permeability and was originally referred to as vascular permeability factor.
Elevated levels of this protein is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy.

Introduction
Acidic fibroblast growth factor is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein functions as a modifier of endothelial cell migration and proliferation, as well as an angiogenic factor. It acts as a mitogen for a variety of mesoderm- and neuroectoderm-derived cells in vitro, thus is thought to be involved in organogenesis. Three alternatively spliced variants encoding different isoforms have been described. The heparin-binding growth factors are angiogenic agents in vivo and are potent mitogens for a variety of cell types in vitro. There are differences in the tissue distribution and concentration of these 2 growth factors.

Introduction
MCSFR which is also familiar as CSF1R, is part of the type3 subfamily of receptor tyrosine kinases. MCSFR is expressed mainly on cells of the monocyte and macrophage lineage, stem cells, and in the growing placenta. Most of the biological effects of this cytokine are mediated by MCSFR. MCSFR contains an extracellular ligand-binding domain, a single membrane-spanning segment, and an intracellular tyrosine kinase domain. Originally CSF1 and this receptor were implicated as vital for normal trophoblastic implantation as well as monocyte development. The role of CSF1/CSF1R in normal mammary gland development is actually very interesting since this connection has also been discovered in the biology of breast cancer with the results of abnormal expression of CSF1 and its receptor. Likewise, in Alzheimer's disease and after brain injuries an increased level of CSF1R was found in the microglia, which causes the microglia to become more active.

Formulation

The protein was lyophilized from a concentrated (1mg/ml) solution with 0.02% NaHCO3.

Purity

Greater than 98.0% as determined by:
(a) Analysis by SEC-HPLC.
(b) Analysis by SDS-PAGE.

Biological Activity

Binding assays of the 125I-Gealthead Seabream IGF1 to Gilthead Seabream or carp (Cyprinus carpio) sera resulted in high specific binding, indicating the existence of one or more IGF-binding proteins. In binding experiments to crude Gilthead Seabream brain homogenate, using human (h) IGF-I as a ligand, the respective IC50 value of hIGF1 was about fourfold lower than that of Gilthead Seabream IGF-1. Recombinant Gilthead Seabream IGF-1 exhibited mitogenic activity in a mouse mammary gland-derived MME-L1 cell line which was approximately 200-fold lower than that of hIGF1. Binding experiments to intact MME-L1 cells suggests that this difference most likely results from a correspondingly lower affinity for IGF1 receptor in these cells. In contrast, the activities of Gilthead Seabream IGF-I and hIGF-I measured by 35S uptake by gill arches from the goldfish (Carassius auratus) were identical, indicating that the recombinant Gilthead Seabream IGF-I is biologically active.

Introduction
The somatomedins, or IGFs, comprise a family of peptides that play important roles in mammalian growth and development. IGF1 mediates many of the growth-promoting effects of GH. Early studies showed that GH did not directly stimulate the incorporation of sulfate into cartilage, but rather acted through a serum factor, termed 'sulfation factor,' which later became known as somatomedin. Three main somatomedins have been characterized: somatomedin C (IGF1), somatomedin A (IGF2), and somatomedin B.
Synonyms
Somatomedin C, IGF-I, IGFI.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Stability
Lyophilized IGF1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IGF1 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Solubility
It is recommended to reconstitute the lyophilized IGF-1 in sterile 0.4% NaHCO3 adjusted to ph 8-9, not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
