title: Dipyridamole-induced increase in production of rat dopaminergic neurons from mesencephalic precursors.
abstract: Dipyridamole (DIP) was tested for its ability to induce dopaminergic (DA) phenotype in cultures from epidermal growth factor-derived mesencephalic precursor cells. When these cells were incubated in media containing serum, the DA phenotype was rarely expressed. The addition of DIP increased (about 350%) the number of DA cells per neurosphere. Treatment with interleukin-1 alpha also induced a significant increase (about 300%) in the number of tyrosine hydroxylase-positive cells. However, the mixture of the most effective doses of these compounds did not induce a further increase in the number of DA cells. The results suggest that DIP may contribute to more efficient production of DA neurons for transplantation therapies in neurodegenerative diseases, and that this may be related to an enhancement of generation and/or survival of DA cells.
