CD34 is a glycosylated transmembrane protein and represents a well-known marker for primitive progenitor cells derived from blood and bone marrow, especially for hematopoietic and endothelial stem cells. Although the biological functions of CD34 are largely unknown, recent data suggest that CD34 is involved in maintaining progenitor cells in a phenotypically undifferentiated state.
PromoCell offers CD34 + progenitor cells from healthy donor umbilical cord blood. CD34 + progenitor cells contain two main cell subpopulations, hematopoietic and endothelial progenitor cells. Thus, CD34 + progenitor cells are suitable for a number of studies, e.g. Eg directed differentiation into more compromised blood cell types and endothelial lineages.
Rigid quality control tests are performed for each lot of CD34 + progenitor cells. They are routinely characterized by flow cytometry that analyzes viability, cell size, and the presence of significant markers, ie, CD34. Additionally, all cells have been tested for the absence of HIV-1, HIV-2, HBV, HCV, HTLV-1, HTLV-2, and microbial contaminants (fungi, bacteria, and mycoplasmas).
Although tests for HIV-1, HIV-2, HBV, HCV, HTLV-1, and HTLV-2 were negative, cells, like all products of human origin, should be handled as potentially infectious. No test procedure can completely guarantee the absence of infectious agents.
