Another 70 rats underwent bilateral CN crush and were then treated with PBS (n = 10, the crush group), dissociated ADSCs (n = 30, the ADSCs group), and MTs (n = 30, the MTs group), respectively. At day 1, 3, 7, 14 (n = 5), and 28 (n = 10) postsurgery, specimens were harvested for histology. At day 28, 10 rats in each group were examined for erectile function before tissue harvest.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Main Outcome Measures<\/jats:title>\n                    <jats:p>Light microscopy of the dynamic aggregation of the MT, immunohistologic examination of the MTs, the retention and distribution of EdU + ADSCs in the corpus cavernosum (CC), and the penis histological analyses of collagen content, Western blot of functional proteins in MTs, intracavernous pressure recording on CN electrostimulation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Three-day-old MTs became stable and expressed nerve growth factor, vascular endothelial growth factor, C-X-C chemokine receptor type 4, Wnt5a, and collagen IV.
