Fig. 4. (A) Assay to assess binding of granule cells to glial substrates. Asterisks indicate significant differences (P<0.01) in the ability of wild-type and mutant cells to adhere to glia. (B) Comparisons of the relative area occupied by granule cells in the cerebella of P6, P15 and adult normal and mutant mice (*P<0.01). (C) Comparison of the relative number (corrected for areas observed) of TUNEL-positive cells in the EGL and IGL of normal and mutant P6 mice (*P<0.05).
