Embryonic cells inside the blastocyst, which divide and differentiate into cells of all tissues of organism, are called embryonic stem (ES) cells. Using the ES cells for transplantations is one the potential ways in regenerative medicine. The present study deals with two different lines of mouse pluripotent cells: embryonic carcinoma (EC) cells line P19 and ES cells line D3. The in vitro cultivation was performed in basal cultivation medium with fetal bovine serum (FBS) and in addition of leukemia inhibitory factor (LIF) in case of ES cells. The neurodifferentiation was induced by medium without FBS and without LIF in case of ES cells and supported by retinoic acid in case of P19 cells and embryoid bodies cultivation in case of ES cells. Pluripotency and neurodifferentiation of the cells were confirmed by presence of molecular markers of pluripotency and neurodifferentiation in both lines in nondifferentiated and differentiated states. Mouse EC P19 cells were transfected by gene for green fluorescent protein (GFP) and used for transplantation in cerebellum of wild type (WT) and Lurcher (Lc) mutant mice. Nondifferentiated cells (P19) and neuroprogenitors (NPG) derived from these cells were used. The study followed the survival, morphology and localization of the grafts. The survival of both types of GFP...
