CD34 is a transmembrane phosphoglycoprotein protein encoded by the CD34 gene in humans, mice, rats and other species.[5][6][7]
CD34 derives its name from the
Function
The CD34 protein is a member of a family of single-pass transmembrane
CD34 is also an important adhesion molecule and is required for T cells to enter lymph nodes. It is expressed on lymph node endothelia, whereas the L-selectin to which it binds is on the T cell.[15][16] Conversely, under other circumstances CD34 has been shown to act as molecular "Teflon" and block mast cell, eosinophil and dendritic cell precursor adhesion, and to facilitate opening of vascular lumina.[17][18] Finally, recent data suggest CD34 may also play a more selective role in chemokine-dependent migration of eosinophils and dendritic cell precursors.[19][20] Regardless of its mode of action, under all circumstances CD34, and its relatives podocalyxin and endoglycan, facilitates cell migration.[13][19]
Tissue distribution
Cells expressing CD34 (CD34+ cell) are normally found in the
It is important to mention that Long-Term Haematopoietic Stem Cells (LT-HSCs) in mice and humans are the haematopoietic cells with the greatest self-renewal capacity and were shown to be CD34+ and CD38− cell fraction within the lineage-depleted cell population (LIn−).[21][22] Human HSCs express the CD34 marker.[21][23] Later studies have reported that low rhodamine retention identifies LT-HSCs within the Lin−CD34+CD38− population.[24][25][26]
CD34 is expressed in roughly 20% of murine haematopoietic stem cells,[27] and can be stimulated and reversed.[28]
Clinical applications
CD34+ is often used clinically to quantify the number of haemopoietic stem cells for use in haemopoietic stem cell transplantation. This is generally a useful marker for cell dosing although there is some evidence that the CD34+ quantification may not be reliable in some circumstances.[29] CD34+ cells may be isolated from blood samples using immunomagnetic techniques and used for CD34+ transplants, which have lower rates of graft-versus-host disease.[30]
