Exosome intracavernous injection and in vivo imaging. (A) Representative images of DMED rats that underwent intracavernous injection with DiR‐labelled exosomes. (B) The signal intensities of different DiR‐labelled exosomes in DMED rats at different time points after injection are presented as a bar graph. Data are expressed as the mean ± standard deviation. ^* P < .05 compared with the CCSMC‐EXO group. CCSMC‐EXOs: exosomes derived from corpus cavernosum smooth muscle cells; BMSC‐EXOs: exosomes derived from bone marrow stem cells; ADSC‐EXOs: exosomes derived from adipose‐derived stem cells; DMED: diabetes mellitus‐induced erectile dysfunction
