Abstract

Fetal cerebellar cell suspensions, prepared from wild-type (+/+) mice, were implanted bilaterally into the cerebellum of Purkinje cell degeneration’ (pcd) mutant mice, a model of adult-onset recessively inherited cerebellar ataxia, to study the functional effects of the grafts on motor coordination and fatigue resistance in a rotating rod treadmill paradigm. The viability of transplanted Purkinje cells was verified with immunocytochemistry for calbindin-D2sk and for glutamate receptor 2/3 subunits and with in situ hybridisation histochemistry for insulin-like growth factor I mRNA, biochemical markers normally expressed by Purkinje cells in the cerebellum. Sham injections of vehicle did not appreciably modify the performance of pcd mutants in the rota-rod tests. On the other hand, bilateral cerebellar grafts led to a 3.5-fold increase in the time period that recipient pcd mice were able to stay on the rotating drum based on the comparison of mean scores (of three trials) or a 5.5-fold increase based on the comparison of maximum scores (of the three trials). These findings provide evidence for a motor enhancement in the pcd mouse model of hereditary cerebellar ataxia following intracerebellar transplantation of primordial Purkinje cells.
