<p>(A) Expression of NMB protein by AdNMB. HEK293 cells plated on type I collagen-coated dishes, were infected with AdNMB. After 24 h, the medium was replaced with serum-free DMEM, and the medium was collected 2 hours later for ELISA (n = 6 per group). *: P<0.001 vs. AdGFP infection. (B) Expression of NMB mRNA in the penis after AdNMB injection. AdGFP and AdNMB were injected into the penis and total RNA was extracted 7 days after injection. Real time PCR analysis was performed in order to examine the expression of NMB mRNA in the penis (n = 5 per group). *: P<0.01 vs. AdGFP infection.</p
