The prolonged survival of donor hematopoietic stem cells is crucial to the success of bone marrow transplantation. The anti-apoptotic gene Bcl-xL has been shown to promote survival of cells of the erythroid, myeloid and lymphoid lineages. To evaluate a potential therapeutic role for Bcl-xL, we used a retroviral vector to express Bcl-xL in donor cells used for murine bone marrow transplantation. We find that Bcl-xL expression in bone marrow cells facilitates hematopoietic reconstitution (as assessed by total cellularity) without altering cell differentiation. Most importantly, cells reconstituted with Bcl-xL are able to achieve high levels of donor chimerism even in non-ablative conditioning protocols in a syngeneic model of transplantation. Thus, expression of Bcl-xL by donor cells during bone marrow transplantation may provide a means to minimize host conditioning and toxicity while still achieving therapeutic degrees of mixed chimerism.
