Figure 6. Time course of the effect of bilateral cavernosal nerve resection on the cell turnover in the rat corpora cavernosa.
Penile corpora cavernosal sections adjacent to those presented on the preceding figures were subjected to TUNEL and PCNA staining. Top: QIA for TUNEL. Middle: QIA for PCNA; Bottom: The ratio between the total area occupied by cells undergoing cell replication (PCNA+) and the apoptotic index obtained above was established for each animal, and then used to calculate means+/-SEM. * p:<0.05; **: p<0.01; ***p<0.001
