Increases in cell density were found in the cerebellum of MeCP2 A140V mice. Left panels show low power images of cresyl violet stained cerebelli from WT and A140V mice. The A140V cerebellum has noticeably darker staining due to an increase in cell density. Scale bar is 500 μm. Right panels show enlargement of these images demonstrating the differences in cell density. Scale bar is 100 μm. Arrows indicate areas of increased cell density.
