Figure 3: Survival of transplanted BMSCs in cavernous tissue: green fluorescent light CM-DiO labeled BMSCs implanted in the cavernous body were similar in the BMSC and LESWT + BMSC groups 1 day after transplantation. The stem cells in the BMSC group disappeared very quickly, and almost no transplanted stem cells remained at the end. Three days after transplantation, the number of CM-DiO-labeled BMSCs that survived in the cavernous body exhibited minimal change in the LESWT + BMSC group. Four weeks after BMSC transplantation, more CM-DiO labeled BMSCs could be observed in the LESWT + BMSC group compared with the BMSC group. (a and b) One day after transplantation. (c and d) Three days after transplantation. (e and f) Four weeks after transplantation. (a , c and e) BMSC group. (b , d and f) LESWT + BMSC group. Scale bar: 75 mm. BMSC: bone marrow mesenchymal stem cell; LESWT: low-energy shock-wave therapy; CM-DiO: cell marker-DiO.
