Figure 7.
Photomicrographs of trichrome stained sections through the perineums of adult bax/bak DKO females. (A) The BC muscle (arrows) can be seen running along the side of the urethra and between the urethra and rectum. U, urethra; R, rectum. Scale bar = 100 μm. (B) Higher-power view of BC muscle fibers in a bax/bak DKO female. This view was taken at the level of the urethra. There is no obvious attachment site and fibers exhibit a marked waviness. Dorsal is down in both views. Scale bar = 50 μm. [Color figure can be viewed in the online issue, which is available at www.interscience.wiley.com.]
