Abstract

Multipotent neural cell lines were generated via retrovirus-mediated v-myc transfer into murine cerebellar progenitor cells. When transplanted back into the cerebellum of newborn mice, these cells integrated into the cerebellum in a nontumorigenic, cytoarchitecturally appropriate manner. Cells from the same clonal line differentiated into neurons or glia in a manner appropriate to their site of engraftment. Engrafted cells, identified by lacZ expression and PCR-mediated detection of a unique sequence arrangement, could be identified in animals up to 22 months postengraftment. Electron microscopic and immunohistochemical analysis demonstrated that some engrafted cells were similar to host neurons and glia. Some transplant-derived neurons received appropriate synapses and formed normal intercellular contacts. These data indicate that generating immortalized cell lines for repair of, or transport of genes into, the CNS may be feasible. Such lines may also provide a model for commitment and differentiation of cerebellar progenitor cells.
