CD34 is a glycosylated transmembrane protein and represents a well-known marker for primitive blood- and bone marrow-derived progenitor cells, especially for hematopoietic and endothelial progenitors. Although the biological functions of CD34 are largely unknown,recent data suggest that CD34 is involved in maintenance of the progenitor cells in a phenotypically undifferentiated state. AcceGen offers CD34+ Progenitor Cells from the cord blood of healthy donors, produced at AcceGen's cell culture facility. The CD34+ Progenitor Cells contain two main cellular subpopulations, hematopoietic and endothelial progenitor cells. Therefore, CD34+ Progenitor Cells are suitable for a series of studies, e.g. directed differentiation into more committed types of blood cells and endothelial lineages.Immediately after isolation, the freshly prepared CD34+ Progenitor Cells are cryopreserved using AcceGen's proprietary serum-free freezing medium, Cryo-SFM. Each cryo vial contains more than 100,000 viable cells after thawing.
