... from 12-20 week gestations. The transplantation of the stem cells were administered to the MPTP-lesioned mice 7 days after administration of MPTP. The results of this experiment were promising for the future of Parkinson's research. The lesioned mice had a 90% depletion of striatal dopamine and 70% destruction of SNpc neurons, which is similar to that seen in human Parkinson's disease (Liker ... et al. 2003). The results of the study showed that the human fetal stem cells survived at least 90 days in immunocompetent adult MPTP-lesioned mice. Other studies have shown that cell survival i...
