Human Recombinant GDNF
Supplier: STEMCELL Technologies
Glial cell line-derived neurotrophic factor (GDNF) is a neurotrophic factor and a member of the tumor growth factor (TGF)-beta superfamily. The GDNF family of growth factors also includes neurturin, persephin, and artemin, which have seven conserved cysteine residues called cysteine-knots (Treanor et al.). GDNF family ligands signal through binding to specific GDNF-family receptor-α (GFRα) co-receptors and activate the RET receptor tyrosine kinase (Durbec et al.). Four different forms of GFRα co-receptors have been characterized (GFRα 1-4); GDNF binds specifically to GFRα1 prior to forming a complex with RET (Airaksinen and Saarma). GDNF is known to promote survival and morphological differentiation of midbrain dopaminergic neurons in both in vivo and in vitro studies and increases their high-affinity dopamine uptake (Granholm et al.; Lin et al.). GDNF has also been shown to have restorative effects on dying dopaminergic neurons in response to degenerative toxins (Aoi et al.). GDNF, together with Human Recombinant BDNF (brain-derived neurotrophic factor), BrainPhys™ Neuronal Medium, and other supplements, can be used to differentiate human pluripotent stem cell (hPSC)-derived neural progenitor cells into neurons (Bardy et al.).

Mouse Recombinant IL-17A
Supplier: STEMCELL Technologies
Interleukin 17A (IL-17A) is the founding member of the family of cytokines that includes Interleukin 17B through Interleukin 17F. It is a potent proinflammatory cytokine that plays a key role in defense against pathogens. IL-17A and IL-17F signal as homodimers or heterodimers through the same receptor, and activate NF-kB, MAPK, and C/EBP pathways (Gaffen). IL-17A receptor is expressed on a variety of cell types, including hematopoietic cell compartments. IL-17A is produced by T helper 17 cells, CD8+ T cells, γδ T cells, natural killer T cells, B cells, neutrophils, innate lymphoid cells and mesenchymal stromal cells (MSCs; Zenobia and amp; Hajishengallis; Mojsilovic et al.). IL-17A receptor is expressed at particularly high levels on stromal cells, including MSCs. IL-17A increases the frequency and the average size of colony-forming units-fibroblast derived from bone marrow, as well as the proliferation of bone marrow-derived MSCs. IL-17A suppresses osteogenic differentiation and bone formation of bone marrow-derived MSCs. The action of IL-17A on hematopoiesis is deeply reliant on the microenvironment and the induction of other regulators. In healthy mouse bone marrow, IL-17A stimulates myeloid and early stage erythroid progenitor cells but inhibits late stage erythroid progenitor cells (Mojsilovic et al.).

Human Recombinant BDNF
Supplier: STEMCELL Technologies
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 et al.). BDNF binds with high affinity to the tropomyosin receptor kinase B (TrkB), and activates AKT and ERK pathways (Mattson et al.). 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 et al.). 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).

Human Recombinant IL-33
Supplier: STEMCELL Technologies
Interleukin 33 (IL-33) is a pro-inflammatory cytokine from the IL-1 family. It binds to ST2 receptor and activates NF-κB and MAPK pathways. IL-33 is expressed by epithelial cells, smooth muscle cells, and fibroblasts in various tissues and organs, as well as resting basophils, mast cells, eosinophils, natural helper cells, group 2 innate lymphoid cells, dendritic cells, and activated macrophages (Schmitz et al.; Yasuda et al.). It contributes to allergic inflammation by stimulating production of the cytokines IL-4, IL-5, and IL-13, and stimulates host defense against microbial and viral infections (Liew; Yasuda et al.). In the central nervous system, IL-33 is produced by endothelial cells and astrocytes. It induces proliferation of microglia and mediates production of pro-inflammatory cytokines (Yasuoka et al.).

Mouse/Rat Recombinant RANTES (CCL5)
Supplier: STEMCELL Technologies
RANTES (regulated upon activation, normal T cell expressed and secreted), also known as CCL5, is a member of the CC family of chemokines and is able to recruit leukocytes to sites of inflammation (Schall et al.). RANTES is secreted by T lymphocytes, macrophages, platelets, synovial fibroblasts, tubular epithelium, and certain types of tumor cells (Aldinucci and Colombatti; Soria and Ben-Baruch). This chemokine exerts its effect by interacting with the chemokine receptors CCR1, CCR3, CCR4, and CCR5. RANTES plays an active role in recruiting a variety of leukocytes into inflammatory sites, including T cells, macrophages, eosinophils, and basophils. In collaboration with certain cytokines that are released by T cells such as IL-2 and IFN-γ, RANTES also induces the activation and proliferation of NK cells to generate CC chemokine-activated killer cells, which are highly cytolytic (Lv et al.; Maghazachi et al.). It has been shown that RANTES produced by CD8+ T cells inhibits HIV infection of primary human peripheral blood mononuclear cells (Appay and Rowland-Jones; Cocchi et al.).

Human Recombinant EGF
Supplier: STEMCELL Technologies
Epidermal growth factor (EGF) 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 et al.). Central nervous system stem cells also proliferate in response to the EGF stimulus (Reynolds and Weiss).

Human Recombinant IGF-I
Supplier: STEMCELL Technologies
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 et al.). 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 et al.).

Human Recombinant Noggin (CHO-expressed)
Supplier: STEMCELL Technologies
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.).
