Prostate enlargement and altered urinary function are part of the aging process

Figure 4. Aging has no impact on percentage of smooth muscle cells. (A) Representative image of smooth muscle α-actin (SMA) staining within the AP in young mice. (B) Representative image SMA staining within the AP in aged mice. (C) Quantitation of percent SMA within the AP shows no difference with age. (D) Representative image of SMA staining within the VP in young mice. (E) Representative image SMA staining within the VP in aged mice. (F) Quantitation of percent SMA within the VP shows no difference with age. (G) Representative image of SMA staining within the DLP in young mice. (H) Representative image SMA staining within the DLP in aged mice. (I) Quantitation of percent SMA within the DLP shows no difference with age. (J) Representative image of SMA staining within the prostatic urethra of young mice. (K) Representative image SMA staining within the prostatic urethra of aged mice. (L) Quantitation of percent SMA around the urethral lumen within the prostatic urethra shows no difference with age.
