Immunohistochemical detection of SRY protein expression in murine bowel. A. Positive control in male murine bowel. B. Negative control in female murine bowel. C. A dispersed expression was detected in the mucosal and submucosal layers of the bowel of female mice 3 days after receiving MSCs from male mice. D. Colonies were detected in the bowel of female mice 7 days after receiving homogeneous MSCs transplants from male mice. E. SRY protein expression in the female murine bowel after 14 days of male MSCs transplantation. F. Enhanced SRY expression was still noted at day 21 days post transplantation. Magnification is 100 ×.
