Mouse Recombinant Hematopoietic Stem Cell Expansion Protein Bundle (from E. coli)

Catalog Number: (77753-602)
Supplier: VWR International
Description: 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. The combination of these cytokines allows for the ex vivo expansion of the most immature hematopoietic stem cells in cord blood or bone marrow preparations, but can be supplemented with other cytokines to promote specific lineages.

Mouse Recombinant Rank Ligand (from E. coli)

Supplier: VWR International
Description: Receptor activator of nuclear factor kappa-B Ligand (RANK Ligand) is a cell-bound marker related to the tumor necrosis factor (TNF) family of proteins. RANK Ligand plays a critical role in bone metabolism and osteoclast differentiation. T cell expression of RANK Ligand promotes dendritic cell maturation.

Pig Recombinant FLT-3 Ligand (from E. coli)

Supplier: VWR International
Description: Fms-related tyrosine kinase 3 ligand (FLT-3 ligand) is a growth factor that regulates hematopoietic cell proliferation. FLT-3 ligand signaling is transmitted through the fms-related tyrosine kinase 3 (FLT-3) receptor. FLT-3 ligand promotes the long-term expansion and differentiation of pro-B cells in the presence of interleukin 7 (IL-7) or in combination of IL-7 and interleukin 3 (IL-3).

Human Hematopoietic Progenitor Cell Expansion Recombinant Protein Bundle

Catalog Number: (77753-604)
Supplier: VWR International
Description: 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.
