Human/Mouse Recombinant TGF-B 3 (from E. coli)
Supplier: Shenandoah Biotechnology
Transforming growth factors (TGFs) are multifunctional peptides that regulate growth and differentiation in most cell types. The TGF-β family of proteins signal through serine/threonine kinase receptors. TGF-β isoforms (TGF-β1, -β2, and –β3) have overlapping, yet distinct biological actions in developing and adult tissues. TGF-β3 is an important factor in regulating cell adhesion and accelerating wound repair. TGF-β3 also functions during osteoblast proliferation, chemotaxis, and collagen synthesis.

Mouse/Rat Recombinant FGF-acidic (from E. coli)
Supplier: Shenandoah Biotechnology
Acidic fibroblast growth factor (FGF-acidic), also known as FGF-1, is a potent inducer of DNA synthesis, cell proliferation, and has chemotactic activities. FGF-acidic regulates cardiogenesis through protein kinase C signaling. FGF-acidic also functions as an insulin sensitizer and mediates adipose tissue remodeling. High serum levels of FGF-acidic are associated with type 2 diabetes mellitus (T2DM), suggesting a pathogenic role of FGF-acidic during T2DM.

Human Recombinant Monocyte/DC PB (from E. coli)
Supplier: Shenandoah Biotechnology
Cytokines for expansion and cell culture of mouse hematopoietic stem cells. Hematopoietic stem cells are self renewing pluripotent cells often characterized by the expression of CD34. Studies have shown that decreased expression of CD34 tends to correlate with decreased self renewal properties and pluripotent potential. Culturing CD34+ cells in a cytokine mixture of TPO, SCF, and FLT-3 Ligand for short time periods allows CD34+ cells to proliferate without decreasing CD34 expression, thus retaining their stem cell properties.

Mouse Recombinant Mouse Th17 Cell Polarizing Plus PB (from E. coli)
Supplier: Shenandoah Biotechnology
Cytokines for polarising mouse T cells into Th17 cells. T helper 17 cells (Th17) are a distinct type of T cell subset that are thought to be important in immunity against microbes at the epitilial and mucosal interfaces of the body. Disruption of the regular function or balance of Th17 cells is thought to be involved in several autoimmune diseases and/or opportunistic infections. Th17 cells are characterised by their ability to produce IL-17, IL-22 and IL-21. Th17 cells can be cultured from naive CD4+ T cells by culturing them in the presence of anti-CD3 and anti-CD28 stimulation with recombinant IL-6 and recombinant TGF-β 1. In some cases neutralising antibodies against IL-12, IL-4 and IFNγ are used along with recombinat cytokines IL-1 β, IL-21 and/or IL-23.

Mouse Recombinant Mouse Hpc Expansion PB (from E. coli)
Supplier: Shenandoah Biotechnology
Cytokines for expansion and cell culture of mouse hematopoietic stem cells to progenitor cells. Hematopoietic stem cells are self renewing pluripotent cells often characterized by the expression of CD34. Studies have shown that decreased expression of CD34 tends to correlate with the decreased self renewal properties and pluripotent potential. Culturing CD34+ cells in a cytokine mixture of SCF, FLT-3 Ligand, IL-6 and IL-3 for short time periods allows rapid expansion of immature and more mature hematopoietic progenitor cells in cord blood or bone marrow preparations. If the goal is to only expand the most immature progenitor and stem cells, it is recommended that a combination of TPO, SCF and FLT-3 Ligand are used (Catalog: PB-500-04). Either cytokine combination can also be supplemented with other cytokines to promote specific lineages.
