Summary
Utilizing the method of in situ hybridization, myc-homologous RNA transcripts were detected in histological sections of the newt limb regenerate. A radiolabeled Xenopus myc-cDNA was used as probe. Autoradiographic grains representing myc-homologous RNAs were observed in cells of the thickened wound epidermis, irrespective of the layer examined. Further, mesenchymatous-like cells which form the blastema also contained multiple grains, indicating that these cells possess myc-like RNA molecules. The presence of RNAs, homologous to the myc proto-oncogene in cells of the regenerating newt limb indicate that a myc-related gene is expressed in these cells during the regenerative process and, therefore, may play an important regulatory role, as myc gene expression has been implicated in the control of cellular proliferation in other systems. Our results are discussed against the background of literature on c-myc proto-oncogene expression.
