Aim:
To investigate the occurrence of immunological rejection in brain transplantation of neural stem cells (NSCs) in the rat of Parkinson's disease model.
Methods:
NSCs derived from the brain of E14.5d SD rat were cultured in vitro. Single cell suspensions were grafted into the striatum of the rat model of Parkinson's disease. Surviving animals were sacrificed at 10, 21, 35 and 60 d after transplantation, and the brain tissue was stained with HE and immunocytochemically to detect the expression of tyrosine hydroxylase (TH), CD4, CD8 and major histocompatibility complex class II antigens (MHC-II).
Results:
The expression of elicited CD4, CD8 and MHC-II was detected within and around the allografts in the graft groups at 10 and 21 d after grafting and was subsiding at 35 d. At 60 d only very occasional immunopositive cells were present. The number of TH positive neurons was low at 10, 21 d, but increased at 35 d and 60 d. There was no significant difference between negative and positive control groups at different time points. The rotation behavior of PD was decreased 35 d after transplantation.
Conclusion:
Intracerebral transplantation of NSCs did not cause remarkable immunological rejection.
