Figure 3. Total number of BrdU-positive cells counted in eight random retinal sections from 12-week-old rats. See Methods for further details. The results are expressed as the mean±SEM; asterisk (*) is p=0.02 versus CT- spontaneously hypertensive rats (SHR). The number of BrDU positive cells present in retina from WKY rats is very low and do not change according to experiment condition (presence of experimental diabetes); by contrast in SHR rats, it is observed a higher number of these BrDU cells in retina and the induction of diabetes dramatically reduced this number abbreviations used are as follows: control WKY (CT-WKY), diabetic WKY (DM-WKY), control SHR (CT-SHR), and diabetic SHR (DM-SHR).
