CD34 is a membrane glycophosphoprotein expressed by endothelial cells (EC), particularly small vessel EC, and hematopoietic stem and progenitor cells1. Note that the MEC14.7 mAb does not stain as many bone marrow cells as other mouse CD34 mAbs, which is probably due to differences in the glycosolated epitope recognized by each Ab. A sulfated form of CD34 is one of the leukocyte L-selectin counterligands and participates in leukocyte adhesion and homing during the inflammatory process1. CD34 is widely used as a marker to select early hematopoietic stem and progenitor cells in hematopoiesis studies1.
