Characterization of the chondrogenic and osteogenic potential of male and female human muscle-derived stem cells: Implication for stem cell therapy.

People of all backgrounds are susceptible to bone and cartilage damage, and these injuries can be debilitating. Current treatments for bone and cartilage injuries are less than optimal, and we are interested in developing new approaches to treat these diseases, specifically using human muscle-derived stem cells (hMDSCs). Our lab previously demonstrated that sex differences exist between male and female murine MDSCs; thus, this paper sought to investigate whether sex differences also exist in hMDSCs. In the present study, we characterized the chondrogenic and osteogenic sex differences of hMDSCs in vitro and in vivo. We performed in vitro osteogenic and chondrogenic differentiation using hMDSC pellet cultures. As demonstrated by microCT, histology, and immunohistochemistry, male hMDSCs were more chondrogenic and osteogenic than their female counterparts in vitro. No differences were observed based on the sex of hMDSCs in osteogenic and chondrogenic gene expression and cell surface markers. For our in vivo study, we transduced hMDSCs with lenti-BMP2/GFP and transplanted these cells into critical-sized calvarial defects in mice. MicroCT results revealed that male hMDSCs regenerated more bone at 2 weeks and demonstrated higher bone density at 4 and 6 weeks than female hMDSCs. Histology demonstrated that both male and female hMDSCs regenerated functional bone. Clinical relevance: These studies reinforce that stem cells isolated from male and female patients differ in function, and we should disclose the sex of cells used in future studies. Considering sex differences of hMDSCs may help to improve cell-based therapies for autologous cell treatment of bone and cartilage damage. This article is protected by copyright.
