Fig. 7.
Smooth muscle cells in the circular smooth muscle layer of colons from smBrg1 knockout and smBrg1/Brm double knockout mice are disorganized. (A and B) Ultrastructure analysis, using H&E staining, of neonatal smBrg1 knockout mice and littermate global Brg1 heterozygous controls (A) and neonatal smBrg1/Brm double knockout mice and global Brg1 het/Brm knockout controls (B). Arrowheads point to cells within the circular smooth muscle layer. (C) Electron micrographs of colons from 3-month-old smBrg1 knockout mice and littermate global Brg1 heterozygous controls. Boxed areas in the left panels are magnified in the right panels. Arrowheads point to the cell borders.
