Fig. 4From: Sustained density of neuroendocrine cells with aging precedes development of prostatic hyperplasia in spontaneously hypertensive ratsEstimated total weight of epithelium and stroma in the ventral lobe per body in rats. Grey columns, SHR; white columns, WKY. The estimated total weights of the epithelium and stroma in the ventral lobe per body weight (mean ± S.E.) in SHR vs. WKY were 0.38 ± 0.04 vs. 0.40 ± 0.05 in 8-week old rats (p = 0.624), 0.48 ± 0.04 vs. 0.45 ± 0.02 in 12-week old rats (p = 0.303), 0.46 ± 0.02 vs. 0.42 ± 0.02 in 16-week old rats (p = 0.090), 0.52 ± 0.02 vs. 0.43 ± 0.03 in 28-week old rats (p = 0.03) and 0.55 ± 0.04 vs. 0.41 ± 0.02 in 56-week-old rats (p = 0.014). Significant differences in weight were observed between SHR and WKY at 28 and 56 weeks of ageBack to article page
