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.

Human Hematopoietic Progenitor Cell Expansion Recombinant Protein Bundle (rh SCF, rh FLT-3 Ligand, rh IL-6, rh IL-3) (from E. coli)
Supplier: Shenandoah Biotechnology
Cytokines for expansion and cell culture of human 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-500-03). Either cytokine combination can also be supplemented with other cytokines to promote specific lineages.

Human Recombinant PLGF-3 (from E. coli)
Supplier: Shenandoah Biotechnology
Placenta growth factor (PlGF) is a member of the vascular endothelial growth factor (VEGF) family and promotes endothelial cell growth and angiogenesis.

Circulating PlGF levels are correlated with colorectal and renal cancers, as well as atherosclerosis and ischemic heart disease. There are four alternatively spliced PlGF isoforms (PlGF-1, PlGF-2, PlGF-3, and PlGF-4), each with unique secretion patterns and heparin-binding affinities. PlGF-3 lacks a heparin-binding domain and signals through the VEGFR-1 receptor.

Human Recombinant FGF-7/KGF (from E. coli)
Supplier: Shenandoah Biotechnology
