FIG. 2.

Measurements of leak point pressure (LPP) values and histology of urethral sphincters at 14 days after cell-free control and adipose-derived cell implantation. (A) At 14 days, the LPP of the cell-implantation group was significantly higher compared with the cell-free control group (*p<0.05). (B) The cell-free control injected urethra remained gaped opened and flaccid with loss of muscle tissues. (C) The injured internal urethral orifices with implanted cells were slightly closed due to bulking effects of the implanted cells (arrows).
