Description: Brain-derived neurotrophic factor (BDNF), like nerve growth factor (NGF), neurotrophin-3 (NT-3), and neurotrophin-4 (NT-4), is a member of the NGF family of neurotrophins, which are required for the differentiation and survival of specific neuronal subpopulations in both the central and the peripheral nervous systems (Minichiello and Klein; Minichiello <i>et al.</i>). BDNF binds with high affinity to the tropomyosin receptor kinase B (TrkB), and activates AKT and ERK pathways (Mattson <i>et al.</i>). It is expressed in the hippocampus, cortex, and synapses of the basal forebrain. BDNF acts as a survival factor for human embryonic stem cells when plated on either feeder cells or Corning® Matrigel® (Pyle <i>et al.</i>). BDNF regulates synaptic transmission and plasticity at adult synapses in the central nervous system, and contributes to adaptive neuronal responses including long-term potentiation, long-term depression, certain forms of short-term synaptic plasticity, and homeostatic regulation of neuronal excitability (Reichardt). It also has a role in neurogenesis by promoting survival and growth of dorsal root ganglion cells, and hippocampal and cortical neurons (Binder and Scharfman). BDNF, together with glial cell line-derived neurotrophic factor (GDNF) and other supplements, is commonly used to differentiate human pluripotent stem cell (hPSC)-derived neural progenitor cells into neurons (Brafman).

Description: Insulin-like growth factor 1 (IGF-I) is a polypeptide that 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 and also activates ERK1/2 signaling. IGF-I is required for embryonic development, and it is produced mainly in the 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 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>). This product is animal component-free.

Description: A member of the pentraxin family of proteins, C-reactive protein (CRP) plays important roles in host defenses, including regulating complement activation in vivo (Sjoberg <i>et al.</i>), decreasing nitric oxide production, and inhibiting angiogenesis in vitro (Verma <i>et al.</i>, 2002). At specific concentrations, CRP directly inhibits endothelial progenitor cell (EPC) differentiation, survival, and function, and is thus implicated in the development of cardiovascular diseases (Verma <i>et al.</i>, 2004). CRP is primarily synthesized by liver hepatocytes, but also by other immune cells, such as macrophages and lymphocytes (Sproston and Ashworth). The expression of this acute-phase protein is induced by IL-6 and IL-1 secretion of macrophages and T-cells during inflammation. For consistency and reproducibility across your applications, C-reactive protein from STEMCELL comes lyophilized with ≥ 87% purity, and endotoxin levels are verified to be ≤1.0 EU/μg protein.

Catalog Number: (MSPP-781041006)

Supplier: STEMCELL Technologies

Description: Amphiregulin is a member of the epidermal growth factor (EGF) family. It binds to several receptors including EGFR/ErbB1, HER2/ErbB2, HER3/ErbB3, and HER4/ErbB4, which activates Ras/Raf/MAPK and PI3K/AKT pathways. This results in cell proliferation, apoptosis resistance, and invasive behaviour (Normanno <i>et al.</i>). The expression of amphiregulin is induced by tissue injury and inflammation. Amphiregulin promotes mammary development, trophoblast growth, lung and kidney branching morphogenesis, and keratinocyte proliferation. It stimulates the growth of most cell types, including normal and transformed mammary epithelial cells, and malignant cells of the colon, prostate, cervix, and pancreas (Berasain and Avila).

Description: Macrophage colony-stimulating factor (M-CSF) is a homodimeric glycoprotein growth factor that regulates proliferation and differentiation of myeloid hematopoietic progenitors to mononuclear phagocytic cell lineages, including monocytes, macrophages, and osteoclasts. M-CSF is a crucial factor for the development of tissue-resident macrophages in most tissues (Ginhoux andamp; Jung). It is required for the maturation and activation of monocytes and macrophages, and regulates inflammatory responses in conjunction with other stimuli such as IFN-γ, LPS, and IL-4 (Murray <i>et al.</i>). M-CSF is also required for bone resorption by osteoclasts, and is involved in the development and regulation of placenta, mammary gland, and brain. M-CSF is produced by monocytes, fibroblasts, osteoclasts, stromal cells, endothelial cells, and tumor cells (Chockalingam andamp; Ghosh). M-CSF exerts its biological effects by signaling through a receptor tyrosine kinase (CSF-1R or M-CSF-R) encoded by the c-fms proto-oncogene (Hamilton). CSF-1R shares similar structural features with other growth factor receptors, including the stem cell factor (SCF) receptor, platelet-derived growth factor receptor (PDGF-R), and Flt3/Flk-2 receptor tyrosine kinase. Stimulation of the CSF-1R upon binding to M-CSF activates MAPK, PI3K, and PLCγ signaling pathways (Chockalingam andamp; Ghosh). Human and mouse M-CSF sequences are highly conserved both at nucleotide and amino acid levels (80% homology; DeLamarter <i>et al.</i>). This product is animal component-free.

Description: Heparin-binding epidermal growth factor (EGF)-like growth factor (HBEGF) is a member of the EGF family (Nishi and Klagsbrun). HBEGF promotes blastocyst adhesion to the uterine wall (Iwamoto and Mekada). It also plays a role in smooth muscle cell hyperplasia and brain injury (Nishi and Klagsburn). HBEGF produced by CD4+ T cells promotes wound healing by stimulating migration and proliferation of keratinocytes, fibroblasts, and smooth muscle cells (Blotnick <i>et al.</i>). It binds to EGFR, ErbB4, ErbB2, and ErbB3, activating the PI3K/AKT signaling cascade (Iwamoto and Mekada). HBEGF is produced in a variety of cells, where it contributes to physiological and pathological processes. HBEGF is overexpressed in ovarian, breast, gastric, colorectal, pancreatic, and endometrial cancers, which likely contributes to pathogenesis (Miyata <i>et al.</i>). This product is animal component-free.

Description: Macrophage inflammatory protein-4 (MIP-4) plays a role in adaptive and innate immune responses, acting as a chemoattractant for T and B lymphocytes, and natural killer cells (Krohn <i>et al.</i>). MIP-4 can also induce immune tolerance through its effects on dendritic cells and macrophages (Azzaoui <i>et al.</i>, Schraufstatter <i>et al.</i>). In breast cancer, MIP-4 has been shown to promote the invasiveness and metastasis of cancer cells in vivo by binding PITPNM3 (Chen <i>et al.</i>).This small cytokine belongs to the chemokine family found only in primates. Based on amino acid sequence, MIP-4 is closely related to MIP-1 alpha (CCL3) and MIP-1 beta (CCL4) (Liang <i>et al.</i>). MIP-4 is produced by antigen-presenting immune cells including dendritic cells, macrophages, and monocytes (Lieshout <i>et al.</i>). For consistency and reproducibility across your applications, macrophage inflammatory protein-4 from STEMCELL comes lyophilized with ≥95% purity, and is verified by LAL analysis to ensure endotoxin levels are ≤1.0 EU/μg protein.
