Assessment of epithelial cell cycling in the regenerating prostate. (a) Experimental design assessing time course of prostate epithelial cell proliferation after testosterone administration (via subcutaneous Alzet pumps). Blue lettering = periods when testosterone is present. Orange lettering = periods when testosterone is absent; (b) Quantification of testosterone-responsive luminal epithelial cell proliferation (by Ki67 positivity in CD24 + EPCAM + cells, quantified by FACS) post testosterone administration. n = 4 mice per condition. ****P < 0.0001. Error bars indicate SEM.
