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 stem cells. CD34+ stem cells are multipotent and can differentiate to all hematopoietic cell types in blood. CD34+ cells can also give rise to all lymphohematopoietic lineages even though they comprise only a small percentage of the cell population. Our CD34+ cells are isolated using positive immunomagnetic cell separation procedures from single or mixed healthy donors. All cord blood is collected in Citric Phosphate with Dextrose Buffer (CPD) from fully consented IRB approved donors.
