Beschreibung: Bone morphogenetic protein 4 (BMP-4) is a member of the highly conserved transforming growth factor β (TGF-β) superfamily. Mature BMP-4 is a disulfide-linked homodimeric protein consisting of two 116-amino-acid residue subunits, and is generated by the proteolytic removal of the signal peptide and propeptides (Xiao <i>et al.</i>). BMP-4 binds to type I and type II receptors on cells. This binding results in the phosphorylation of receptor 1, which in turn results in the phosphorylation of Smad proteins, which then go on to act as transcription factors (Zhang <i>et al.</i>). BMPs have been shown to be key regulators of embryogenesis and are known to play a role in the growth and differentiation of various cell types, including embryonic stem (ES) cells, induced pluripotent stem (iPS) cells, mesenchymal cells, epithelial cells, hematopoietic cells, and neuronal cells (Chadwick <i>et al.</i>; Graham <i>et al.</i>; Jones <i>et al.</i>; Lengerke <i>et al.</i>; Zhang <i>et al.</i>).

Beschreibung: R-Spondin-1 (RSPO1) is the prototype member of the R-Spondin (RSPO) protein subfamily of a superfamily of thrombospondin type 1 repeat (TSR-1)-containing proteins (Chen <i>et al.</i>; Kamata <i>et al.</i>; Kazanskaya <i>et al.</i>; Kim <i>et al.</i>). Although unable to initialize signaling, RSPO family members are potent enhancers of WNT signaling (Cruciat and Niehrs; de Lau <i>et al.</i>; Kamata <i>et al.</i>; Kazanskaya <i>et al.</i>). They are characterized by a TSR-1 domain, a carboxy-terminal region with positively charged amino acids, and two N-terminal furin-like cysteine-rich repeats (Glinka <i>et al.</i>; Kazanskaya <i>et al.</i>). R­-Spondin-1 activates β­-catenin signaling via the WNT signaling cascade and by indirectly increasing low-density lipoprotein receptor-related protein 6 (LRP6) on the cell surface. It does this by binding leucine-rich repeat-containing G-protein-coupled receptor 5 (LGR5), and competing with WNT antagonist DKK­1 for binding to the WNT co­receptors, Kremen and LRP­6, which reduces DKK­1-­mediated internalization of LRP6 (Binnerts <i>et al.</i>). RSPO1 is involved in a wide range of pleiotropic roles during embryogenesis, it is required for the specification of hematopoietic stem cells, and it has been shown to be important in the growth, survival, and migration of ovarian cancer cells (Cruciat and Niehrs; de Lau <i>et al.</i>; Genthe and Clements; Liu <i>et al.</i>).

Beschreibung: Receptor activator of nuclear factor kappa-B ligand (RANKL) is a member of the tumor necrosis factor (TNF) superfamily (Anderson <i>et al.</i>). Cytokines in the TNF superfamily are involved in a variety of long-term cellular activities such as differentiation, proliferation, and cell death (MacEwan). RANKL is a type II homotrimeric transmembrane protein expressed in both a membrane-bound and secreted form (Ikeda <i>et al.</i>). RANKL binds to the receptor activator of nuclear factor kappa-B (RANK). Upon binding to its receptor, RANKL activates the AKT signaling pathway (Moon <i>et al.</i>). Osteoprotegerin (OPG) may also bind RANKL, and this binding competes with RANKL-RANK binding (Lacey <i>et al.</i>). RANKL is involved in osteoclastogenesis (Lacey <i>et al.</i>; Yasuda <i>et al.</i>) and T cell activation (Wong <i>et al.</i>).

Beschreibung: 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).

Beschreibung: 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>).

Beschreibung: 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).
