Abstract

The bone marrow (BM) microenvironment is largely com- prised of mesenchymal stromal cells (MSCs) and is vital in supporting haematopoiesis. Limited studies have indicated that the BM microenvironment is damaged by chemotherapy; however the extent and long-term effects of this are unknown. This may be particularly critical in stem cell transplant patients who receive high-dose chemotherapy prior to transplant, and whilst the incoming graft replaces haematopoietic cells, the microenvironment remains of host origin. Consequently, dam- age caused by chemotherapy may be permanent and possibly implicated in graft failure if haematopoietic support is com- promised. MSCs were isolated from BM samples from patients undergoing chemotherapy for haematological malignancies as well as untreated control BM obtained as a waste product dur- ing total hip replacements. Following chemotherapy, MSCs have reduced proliferative capacity and survival (p
