Fig. 4.

Quantitative analysis of the phenotypic repertoire generated by embryonic (dark gray) and postnatal (light gray) cerebellar cells transplanted to the embryonic rat brain in utero. For each experimental set, three representative cases are illustrated (indicated on thez-axis). The different neuron phenotypes are represented as the percentage on the total number of transplanted nerve cells observed in the relevant brain. Granule cells generated by embryonic progenitors in the lower brainstem are not included in these counts that were performed on sections encompassing mesencephalon and forebrain, where no granule neurons were found. gc, Granule cells; mli, molecular layer interneurons;pc, Purkinje cells; mn, multipolar neurons.
