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 PI3K signaling cascades (Schuster et al.). 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 et al.; Oppenheim et al.). CNTF has also been shown to protect rod photoreceptors from light-induced damage and have therapeutic effects on retinal degenerative diseases caused by genetic defect or damage induced by toxins, autoantibodies, or strong light (Pernet et al.; Rhee et al.). Another therapeutic role of CNTF has been reported in protecting oligodendrocytes from death induced by apoptosis (Louis et al.). Additionally, CNTF is commonly used to differentiate human pluripotent stem cell (hPSC)-derived neural progenitor cells into astrocytes (Krencik and Zhang). This product is animal component-free.

Vascular endothelial growth factor (VEGF-165) is a heparin-binding homodimeric glycoprotein involved in embryonic vasculogenesis and angiogenesis. VEGF binds to VEGFR-1 (R1) and VEGFR-2 (R2), and activates Raf/MEK/ERK and PI3K/AKT pathways (Ferrara et al.). It plays an important role in neurogenesis both in vitro and in vivo (Storkebaum et al.). It has neurotrophic effects on neurons of the central nervous system and promotes growth and survival of dopaminergic neurons and astrocytes. VEGF also promotes growth and survival of vascular endothelial cells, monocyte chemotaxis, and colony formation by granulocyte-macrophage progenitor cells (Ferrara et al.).

Use autotaxin (ENPP2) to catalyze the production of lysophosphatidic acid (LPA), a potent mitogen that can evoke growth factor-like responses (Moolenaar and Corven), from lysophospholipids in extracellular fluids. Autotaxin is a secreted glycoprotein that belongs to the ectonucleotide pyrophosphatase/phosphodiesterase (ENPP) family, containing two N-terminal somatomedin B (SMB)-like domains, a central phosphodiesterase (PDE) domain with an active catalytic site, and a C-terminal nuclease-like (NUC) domain (Nishimasu et al.). Dysregulation of autotaxin and LPA receptors is implicated in cancer (Tigyi et al.), fibrosis (Ninou et al.), neurological disorders (Roy et al.), and other inflammation-associated conditions. Both Autotaxin and LPA are overexpressed in many cancers and can promote cell proliferation, migration, and resistance to apoptotic death (Tigyi et al.). Autotaxin was also found to catalyze the production of cyclic phosphatidic acid (CPA), an analog of LPA, which has anti-mitogenic and inhibitory effects on tumor cell invasion and metastasis (Fujiwara). This protein contains a His-residue tag at the amino end of the polypeptide chain. For consistency and reproducibility across your applications, Autotaxin from STEMCELL comes lyophilized with ≥ 85% purity, and endotoxin levels are verified to be ≤1.0 EU/μg protein.

Noggin binds to and antagonizes bone morphogenetic protein (BMP) ligands of the transforming growth factor beta (TGF-β) family. Noggin supports maintenance of undifferentiated human embryonic stem cells in vitro, and can be used to prevent spontaneous differentiation in the short term (Chaturvedi et al.). Noggin is essential for development of structures derived from ectoderm embryonic somite, skeletal patterning, and neurogenesis in vivo. It also influences chondrogenesis, osteogenesis, and joint formation (Krause et al.), and promotes dopaminergic differentiation of embryonic stem cells and subsequent survival of dopamine neurons (Chiba et al.).

Interferon gamma-inducible protein (IP) 10 or CXCL10 is a member of the CXC chemokine family. It binds CXCR3 activating ERK1/2, p38/MAPK, JNK, and PI3-kinase/AKT signaling pathways, inducing intracellular calcium influx, DNA synthesis, cell proliferation, and chemotaxis. IP-10 regulates innate and adaptive immune responses by affecting the function of activated T cells, natural killer cells, inflammatory dendritic cells, macrophages, and B cells. IP-10 is produced by leukocytes, activated neutrophils, eosinophils, monocytes, epithelial cells, endothelial cells, fibroblasts, and keratinocytes in response to IFN-gamma. IP-10 has been implicated in a wide range of diseases, including infectious diseases and chronic inflammatory and autoimmune diseases, as well as in tumor formation (Liu et al.).

Dickkopf-related protein 1 (DKK-1) is a member of the Dickkopf family and is a secreted protein that inhibits the canonical WNT pathway by competitive binding to low-density lipoprotein receptors (LRP)-5 and 6 with high affinity, thereby decreasing β-catenin protein stability (Niehrs). DKK-1 regulates embryonic development and contains two conserved cysteine-rich domains separated by a linker region and an N-terminal signal peptide (Krupnik et al.; Lieven et al.). A family of human DKK-related genes composed of DKK-1, DKK-2, DKK-3, and DKK-4 have been characterized together with a unique DKK-3 related protein termed Soggy (Krupnik et al.). DKK-1 has been shown to support the generation of myeloid-derived suppressor cells (MDSCs) and thus is a negative regulator of antitumor immune responses (D’Amico et al.). DKK-1 from thrombocytes is an important regulator of leukocyte infiltration and induces Th2 cell polarization and potentiates Th2 cell cytokine expression (Chae et al.). DKK-1 has also been shown to drive cardiac and retinal differentiation from induced pluripotent stem (iPS) cells (Lian et al.). Protein contains a His-residue tag at the carboxyl end of the polypeptide chain.
