Figure 7. Periprostatic implantation of MSCs and evaluation of erectile function in CNI rats. The major pelvic ganglia (MPG) and cavernous nerve (CN) were exposed. Periprostatic implantation of MSCs was applied to restore erectile function of CNI rats. The right carotid artery was exposed to measure the mean arterial pressure (MAP). The corpus cavernosa was exposed and a heparinized 23-gauge butterfly needle was inserted into the penile crus and connected to polyethylene-50 tubing to measure the intracavernous pressure (ICP).
