Adult bone marrow-derived stem cells may aid the healing of chronic lower extremity wounds by transplanting a population of progenitor cells locally into the wound. We present results from three cases in which bone marrow aspirate containing marrow-derived cells was applied/injected locally into complex lower extremity chronic wounds of differing aetiologies. Our case series suggest that bone marrow aspirate, applied topically and injected into the wound periphery, may be a useful and potentially safe adjunct to wound simplification and ultimate closure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
