Hematopoietic and mesenchymal stem cells can potentially be the same cell type or adhere simultaneously in both bone marrow (BM) and muscle. In this study, we asked whether murine BM-derived cells could be tracked in muscle tissue after BM transplantation and whether muscle-derived cells have hematopoietic potential. To answer the first question, we transplanted BM from male BALB/c mice into irradiated female recipients and analyzed for engraftment. We used quantitative polymerase chain reaction (PCR) and fluorescent in situ hybridization techniques for Y chromosome-specific gene probes. A high number of BM-derived cells were located in both the intravascular and extravascular spaces in muscle tissue after BM transplantation. To answer the second question, we analyzed colony-forming potential in vitro with soft-agar assays and the competitive engraftment potential in vivo of muscle-derived cells. Engraftment levels of male cell populations were tested by quantitative PCR. The long-term engraftment potential of muscle-derived cells was low compared with that of BM. We conclude that there is intensive cellular trafficking between BM and muscle tissue. The engraftment potential of muscle-derived stem cells into BM is low and corresponds to the low amounts of hematopoietic colony-forming cells found in muscle tissue.
