Cyclosporin A is used to prevent graft‐versus‐host disease (GvHD) following bone marrow transplantation (BMT) and it has been implicated in reducing the time to engraftment for leukaemia and aplastic anaemia patients. To evaluate the effect of cyclosporin A on engraftment, the proliferative capacity of bone marrow progenitors (CFU‐E, CFU‐F and CFU‐C) was assessed both in vitro and following treatment with cyclosporin A over a 9‐week period using an animal model. Cyclosporin had a differential effect on the haemopoietic progenitors, with the myeloid series unaffected at therapeutic concentrations. Both erythroid and stromal progenitors were significantly inhibited at similar concentrations. The mechanism by which cyclosporin A enhances engraftment remains unclear; however, it is not mediated by enhancing any of the haemopoietic progenitors.
