Significance of increasing adhesion of cord blood hematopoietic cells and a new method: platelet microparticles.

Hematopoietic recovery after transplantation with cord blood (CB) is slower than with bone marrow (BM) and mobilized peripheral blood. Adhesion molecules (AMs) on hematopoietic cells are involved in hematopoietic cells' homing. It may be possible to enhance CB CD34+ cells engraftment by increasing their expressions of AM.
