Cord Blood CD34+ Stem/Progenitor Cells
Human cord blood is a rich source of CD34+ hematopoietic stem and progenitor cells. Collection of cord blood is a noninvasive and painless procedure performed at one of our partnering hospitals by our own procurement staff. Fresh whole cord blood is transferred to our FDA registered GLP regulatory-compliant cell manufacturing facility where cord blood CD34+ stem cells are processed, analyzed, and vialed. Cell attributes, such as phenotype, viability, purity, and cell count, are checked to meet rigorous standards ensuring high-quality cells before leaving the facility.
