Macrophage colony stimulating factor (M-CSF) is a hematopoietic growth factor that is widely produced by a variety of cells. M-CSF stimulates the proliferation and differentiation of hematopoietic stem cells into monocyte and macrophage cell types. M-CSF also acts through the colony stimulating factor 1 receptor (CSF1R) to modulate processes involved in immunology, bone metabolism, fertility, and pregnancy. Human M-CSF shows activity on mouse cells; however, mouse M-CSF shows no activity on human cells.

Epstein-Barr virus induced gene 3 (EBI3) is a secreted glycoprotein belonging to the hematopoietin receptor family related to the p40 subunit of interleukin 12 (IL-12). EBI3 expression is induced in B-lymphocytes in response to Epstein-Barr virus infection.  EBI3 forms heterodimers with p28 to form interleukin 27 (IL-27), and with p35 to form interleukin 35 (IL-35).  Both IL-27 and IL-35 have anti-inflammatory and regulatory activity.

Interleukin 7 (IL-7) is a hematopoietic cytokine that is an important regulator of B and T cell development. IL-7 is secreted by bone marrow and thymic stromal cells, dendritic cells, intestinal epithelial cells, hepatocytes, and keratinocytes. IL-7 signals through the interleukin 7 receptor (IL-7R) to promote the differentiation of hematopoietic stem cells into T cells, B cells, and natural killer cells. IL-7 is also a regulator of intestinal mucosal lymphocyte proliferation. Human and mouse IL-7 show species cross-reactivity.

Insulin-like growth factor I (IGF-I) is a growth factor that is produced by the liver. IGF-1 production is stimulated by growth hormone (GH). IGF-I binds the insulin-like growth factor 1 receptor (IGF1R) and the insulin receptor to stimulate systemic body growth. IGF-I is one of the most potent activators of the AKT signaling pathway, which stimulates cell proliferation and inhibits programmed cell death. Mature human IGF-I is 100% homologous to bovine and porcine IGF-1 proteins.

Pleiotrophin (PTN) is a heparin-binding growth factor that has mitogenic effects on fibroblast, epithelial, and endothelial cells. PTN is made by many tissues, but is predominantly secreted by nervous tissue during development. PTN induces neurite outgrowth and is involved in tumor growth and metastasis. PTN binds with low affinity to the cell surface receptor nucleolin to inhibit HIV-1 infection. PNT also binds the receptor protein tyrosine phosphatase type Z (PTPRZ), syndecan-3, and anaplastic lymphoma kinase (ALK) receptors.

Growth differentiation factor 15 (GDF-15) is a member of the transforming growth factor beta (TGF-β) family and is made by the placenta and cardiovascular tissues. GDF-15 regulates inflammatory and apoptotic pathways during cellular stress and injury. GDF-15 is emerging as a biomarker of early heart disease, such that increased levels of circulating GDF-15 are associated with an increased risk of developing heart failure. The GDF-15 D variant has a Histidine to an Aspartate substitution at amino acid position 7.

Interferon gamma (IFN-γ) is a type II interferon that is critical during adaptive and innate immune responses to infection. IFN-γ is produced by T cells and natural killer cells following antigen-specific activation. IFN-γ binds IFN-γ receptors (IFN-γ R1 and IFN-γ R2), which are expressed on most immune cells, to activate the JAK-STAT pathway. IFN-γ-induced signaling increases the expression of class 1 major histocompatibility complex (MHC) molecules. Human IFN-γ is not cross-reactive with mouse IFN-γ.

Platelet-derived growth factor (PDGF) serves as a crucial controller of cell growth, proliferation, and angiogenesis. PDGF exists as a dimeric glycoprotein, comprising two polypeptide chains (A and B) stabilized by disulfide bridges. These chains can combine to form either heterodimers (PDGF-AB) or homodimers (PDGF-AA and PDGF-BB) PDGF-AA is commonly used for differentiation of neural progenitor cells derived from human pluripotent stem cells (hPSC) into oligodendrocyte precursor cells.

Transforming growth factors (TGFs) are multifunctional peptides that regulate growth and differentiation in most cell types. The TGF-β family of proteins signal through serine/threonine kinase receptors. TGF-β isoforms (TGF-β1, -β2, and –β3) have overlapping, yet distinct biological actions in developing and adult tissues. TGF-β3 is an important factor in regulating cell adhesion and accelerating wound repair. TGF-β3 also functions during osteoblast proliferation, chemotaxis, and collagen synthesis.
