mortality/aging
• mice die at 2 to 4 months of age
|
nervous system
• at P15, Bergmann glial cell processes are severely disorganized
|
• mice exhibit a delay in the migration of cells from the external granule layer to the internal granule layer
|
• reduced at P9
|
• at P9, the external granule cell layer contains more granule cells than in wild-type mice
• unlike in wild-type mice, granule cells are maintained at P17 but migrate to the internal granule cell layer by P21
• however, cell proliferation within the external granule layer is normal
|
• at P9
