Figure 2: Time-dependent disappearance of IC-injected cells. (a) Representative images of CM-Dil-labeled cells retained in corpus cavernosum at days 1, 7, and 14 postinjection in ADSC- and MT-injected rats. Original magnification: Left, ×200 and right, ×1000. (b) Quantitative data of labeled cells between two groups are expressed as integrated optical density (IOD) of CM-Dil-positive area in corpus cavernosum. *P < 0.05 compared with DM + ADSCs group.
