AB - Using in situ nucleic acid hybridisation histochemistry, we have studied the expression of somatostatin mRNA and neuropeptide Y mRNA in grafts of embryonic striatal neurones implanted into the ibotenic acid-lesioned rat neostriatum. Tissue sections of the grafted striatum were incubated with either 32P- or 35S-labelled complementary oligodeoxyribonucleotide probes specific for somatostatin mRNA and neuropeptide Y mRNA, exposed with X-ray film and dipped in Ilford K-5 emulsion. Neither somatostatin mRNA nor neuropeptide Y mRNA was detectable in the ibotenic acid-lesioned striatum indicating a pronounced degeneration of somatostatin- and neuropeptide Y-containing neurones. However, in the striatal grafts the levels of somatostatin mRNA and neuropeptide Y mRNA were substantially increased over those in the control intact striata. The results suggest that in the grafts, somatostatin mRNA and neuropeptide Y mRNA were expressed in a higher proportion of primordial striatal neurones and there was also an increased level of expression of each neuropeptide gene per individual neurone (reflecting a higher synthetic activity of such neurones) compared to the intact mature striatum. These data demonstrate the sensitivity of the in situ hybridisation technique to study patterns of gene expression in developing neuronal tissues after transplantation.
