Abstract:

BACKGROUND: Studies have shown that embryonic stem cell transplantation may improve learning and memory abilities in rats with vascular dementia, enhance neural plasticity, stereotaxically migrate and differentiate into mature neurons.
OBJECTIVE: To investigate the improvement of Parkinson disease rats following the neuroepithelial stem cells were transplanted into the brain and the migration of the transplanted cells.
METHODS: The neuroepithelial stem cells derived from green fluorescent protein transgenic mice were stereotaxically transplanted into the substantia nigra, striatum and lateral cerebral ventricle of Parkinson disease rats. The survival, migration and differentiation of transplanted neuroepithelial stem cells were examined at different time of transplantation, and the relationship between the change of rotation behavior and content of dopamine were analyzed. Therapeutic effects of embryonic neuroepithelial stem cells transplantation in Parkinson disease rats were assessed.
RESULTS AND CONCLUSION: Transplanted cells survived well and were positive for tyrosine hydroxylase. Cells migrated from the transplanted region to the substantia nigra. The rotational behavior of Parkinson’s diseases rats recovered greatly and the dopamine content was raised after the transplantation of neuroepithelial stem cells. These findings indicate that the neuroepithelial stem cells would migrate to the substantia nigra after transplanted into the brain of Parkinson disease rats, and Parkinson disease could be treated following the increasing of dopamine content in the striatum.
