nNOS, RECA-1, α-SMA and Masson’s Trichrome stain data in the experimental animals

Groups	NR+PBS	HR+PBS	HR+ADSC	P value
nNOS (number)	645 ± 92.4	489 ± 73.9	859 ± 79.5 †	0.0169
RECA-1 percentage (%)	7.4 ± 0.82	4.1 ± 0.63 *	7.4 ± 1.08	0.0131
α-SMA percentage (%)	10.0 ± 0.97	12.8 ± 0.76	13.7 ± 1.21 ‡	0.0490
SM/collagen ratio	0.12 ± 0.018 *	0.17 ± 0.012	0.18 ± 0.011	0.0119

NR+PBS = rats fed a normal diet that received phosphate buffered saline (PBS), HR+PBS = rats fed a high-fat diet that received PBS, HR+ADSC = rats fed a high-fat diet that received adipose-derived stem cells (ADSC) injection into penis, nNOS = neuronal nitric oxide synthase, RECA-1 = rat endothelial cell antigen-1, α-SMA =α-smooth muscle cell actin, SM = smooth muscle.

One-way analysis of variance (ANOVA) for continuous variables; data is shown as mean ± standard error of the mean.

One each rat in the HR+PBS and HR+ADSC groups suddenly died after ketamine injection and were excluded.
