title: Comparison of embryonic cerebellar graft survival in adult Lurcher mutant mice of strains C3H and C57Bl/7.
abstract: Lurcher mutant mice suffer from complete loss of cerebellar Purkinje cells. The aim of the work was to compare the solid embryonic cerebellar graft survival in adult Lurcher mutant mice derived from strains C3H and C57Bl/7 and to assess the morphology of the grafts. Embryonic cerebellar tissue was obtained from 12-13 days mice embryos expressing green fluorescent protein (GFP). Embryonic cerebellum was injected with a glass microcapillary into the cerebellum of adult Lurcher mutant mouse. Host mice were sacrificed 2-12 weeks after the transplantation. Brainstems and cerebella were examined histologically. The graft and graft derived GFP-positive cells were detected according to their green fluorescence. To visualise the structure of the graft Nissl staining was used. Graft survival percentage was evaluated in groups of mice sacrificed during the first, second or third month after the transplantation. The graft was found in all C57Bl/7 mice and in 90.9% of C3H mice examined within one month after the transplantation. In the second month the graft was present in 83.3% of C57Bl/7 and 50.0% of C3H mice. Till the third month the graft survived in 68.2% of C57Bl/7 mice and 22.2% of C3H mice. In C57Bl/7 mice a cerebellar structure was developed in the graft and migration of graft derived-cells to the host tissue was observed more often than in C3H mice. C567Bl/7 mice seem to be more suitable for experiments testing functional consequences of transplantation into the cerebellum requiring good long-term graft survival.
