Abstract: In order to establish the number, the viability and the developmental potential of GABAergic neurons present in dopaminergic ventral mesencephalic (VM) grafts from embryonic rat, we have studied the survival and development of these neurons in culture. The GABAergic fraction demonstrated a highly disproportionate survival in culture in relation to other VM neurons resulting in a drastic change in the neuronal composition of the dissociated VM grafts. The occurrence of a similar gradual dominance of GABAergic neurons at the site of intracerebral implantation, may affect the development of grafted dopaminergic VM neurons and their interaction with host striatal cells.
