Fig. 8. Bladder smooth-muscle development. (A,B) Smooth-muscle
heavy-chain myosin expressions in the transverse sections of the E14.5
wild-type (A) and p63-/- (B) bladders. The intestinal
muscular wall serves as an internal control (arrow, 100x).
(C,D) Smooth-muscle
-actin actin expressions in the
sagittal section of E18.5 wild-type (C) and p63-/- (D)
bladders (40x). Large arrow in C,D represent the ventral bladder walls.
Small arrow in D represents the dorsal bladder wall. (E,F)
Hematoxylin and Eosin staining of E18.5 wild-type (E) and
p63-/- (F) bladders (sagittal sections, 200x).
