Peptide Amphiphile Nanofiber Delivery of Sonic Hedgehog Protein to Reduce Smooth Muscle Apoptosis in the Penis after Cavernous Nerve Resection

PA technology is effective in delivering SHH protein to the penis and SHH is effective in suppressing CN injury‐induced apoptosis. These results suggest substantial translational potential of this methodology and show that only a short duration of SHH treatment is required to impact the apoptotic index.
