Abstract:
:Expression of the chemokine receptor CXCR4 on human haemopoietic stem cells (HSC) may play a crucial role in localising these cells to the bone marrow. To evaluate whether CXCR4 expression is clinically relevant we have enumerated CXCR4-positive HSC used for allogeneic transplantation and sought any relationship with the rate of subsequent haemopoietic reconstitution. CD34-positive progenitor cells were isolated from peripheral blood stem cell (PBSC) collections from 16 normal donors. The proportion of cells co-expressing CXCR4 was enumerated and the times to recipient haemopoietic reconstitution measured. The median frequency of CD34-positive cells co-expressing CXCR4 was 41% (range 16% to 76%) and the median number of CXCR4 CD34 double-positive cells infused at transplantation was 2.5 x 10(6) cells/kg (range 0.8-10.3). Patients receiving >2.5 x 10(6) CXCR4 CD34 double-positive cells/kg demonstrated a significant shortening of time to platelet engraftment compared to the recipients of the lower cell doses (10 days vs 14.5 days, respectively, P = 0.02) with all but one of the recipients of the higher cell doses achieving platelet engraftment by day 11. Co-expression of CXCR4 on CD34-positive progenitor cells may be an important determinant of post-transplant engraftment and in our hands transplantation of a minimum of 2.5 x 10(6) CXCR4 CD34 double-positive cells/kg ensured rapid post-transplant platelet recovery.
