Insulin-like growth factor 1 (IGF-I) is a polypeptide which belongs to the family of insulin-like growth factors that are similar in molecular structure to proinsulin. IGF-I binds to the IGF-I receptor and is a potent activator of the PI3K/AKT pathway; it also activates ERK1/2 signaling. IGF-I is required for embryonic development, and it is produced mainly in liver in response to a hepatocyte growth hormone. In the absence of insulin, IGF-I is necessary for the maintenance of human pluripotent stem cells (Wang <i>et al.</i>). Together with interleukin 3 (IL-3), IGF-I stimulates differentiation and proliferation of myeloid cells, and has been shown to regulate lymphopoiesis by stimulating proliferation and differentiation of T and B cells in lymphoid organs (Heemskerk <i>et al.</i>).

Sonic hedgehog (Shh) is a member of the Hedgehog family of secreted signaling proteins that has a prominent role in patterning during early mammalian development (Ho and Scott). It is expressed during early embryogenesis in a variety of tissues (Finco <i>et al.</i>). During patterning of the central nervous system, Shh directly acts on cells to specify neural cell fates, regulates proliferation and survival of oligodendrocyte precursors and neural crest cells and stimulates proliferation, differentiation, and axon growth (Ho and Scott; Martí). Shh also regulates T cell differentiation and activation (Crompton <i>et al.</i>). Recombinant Mouse Shh is a fully biologically active molecule.

Monocyte chemotactic protein-1 (MCP-1), also known as CCL2, is a member of the CC family of chemokines. The protein is primarily induced by platelet-derived growth factor (PDGF) gene (Cochran <i>et al.</i>). The biological effects of MCP-1 are mediated via the specific G-protein-coupled receptor CCR2 which in turn activates signal transduction pathways leading to monocyte transmigration (Sozzani <i>et al.</i>). Migration of monocytes from the bloodstream across the vascular endothelium is required for routine immunological surveillance of tissues, as well as other immunomodulatory effects. MCP-1 is produced by a variety of cell types, including fibroblasts and endothelial, epithelial, smooth muscle, mesangial, astrocytic, monocytic, and microglial cells, which are important for antiviral responses in the peripheral circulations and in tissues (Cushing <i>et al.</i>; Deshmane <i>et al.</i>). MCP-1 plays a role in physiological processes such as neurogenesis, neuroprotection, and neurotransmission and has important implications in neurological disorders such as multiple sclerosis and Alzheimer’s disease, in which it is produced during neuroinflammation at the sites of lesions (Conductier <i>et al.</i>).

Ciliary neurotrophic factor (CNTF) is a neurotrophic factor that belongs to the four-helix bundle cytokine family and is structurally related to interleukin 6 (IL-6), interleukin 11 (IL-11), leukemia inhibitory factor (LIF), and oncostatin M (OSM). CNTF binds to its receptor CNFTRα and induces formation of a heterodimer of the signal-transducing IL-6 receptor gp130 and LIF receptor (LIFR)-β, which triggers JAK/STAT, ERK, and the PI3K signaling cascades (Schuster <i>et al.</i>). CNTF plays an important role in neurogenesis and the differentiation of neural stem cells and has been suggested to possess a therapeutic role in treating neurological disorders (Ding <i>et al.</i>; Oppenheim <i>et al.</i>). CNTF has also been shown to protect rod photoreceptors from light-induced damage and to have therapeutic effects on retinal degenerative diseases caused by genetic defect or damage induced by toxins, autoantibodies, or strong light (Pernet <i>et al.</i>; Rhee <i>et al.</i>). Another therapeutic role of CNTF has been reported in protecting oligodendrocytes from death induced by apoptosis (Louis <i>et al.</i>). Additionally, CNTF is commonly used to differentiate human pluripotent stem cell (hPSC)-derived neural progenitor cells into astrocytes (Krencik and Zhang).

Omschrijving:
Epidermal growth factor (EGF) is the founding member of the EGF family of proteins and is characterized by high affinity binding to various EGF receptors (EGFRs) and the production of mitogenic responses (Carpenter and Cohen). EGF promotes EGFR dimerization, resulting in activation of downstream pathways including PI3K, ERK1/2, JAK/STAT, β-catenin, and calcium signaling. EGF is secreted by the gut-associated salivary and Brunner’s glands, is found in a variety of body fluids, and stimulates cell proliferation and differentiation in rodent and neonatal human intestine (Wright <i>et al.</i>). EGF can stimulate the proliferation of mouse embryonic stem cells or induce the terminal differentiation/growth inhibition of A431 cells (Heo <i>et al.</i>).
