Background: CD34

CD34 is a glycosylated type I transmembrane protein; it was discovered as a hematopoietic cell-surface antigen (1, 2, 3). Porcine CD33 cDNA encodes a 389 amino acid (aa) precursor that contains a 20 aa signal sequence and a 275 aa extracellular domain (ECD). Within the ECD, porcine CD34 shares 55%, 48% and 44% aa sequence identity with human, mouse, and rat CD34, respectively. This single-pass sialomucin‑like transmembrane protein is heavily glycosylated and phosphorylated by Protein Kinase C (PKC) (4, 5). CD34 is found on multipotent precursors, bone marrow stromal cells, embryonic fibroblasts, vascular endothelia, as well as some populations of mesenchymal stem cells, and tumor cell lines, and it is a common marker for diverse progenitors (6). CD34 is involved in the adhesion of stem cells to the bone marrow extracellular matrix or to stromal cells.
