... prolongs neural proliferation by maintaining a mitotically active neuroblast. In the abdomen, Grh terminates neural proliferation by regulating the competence of neuroblasts to undergo apoptosis in response to Abdominal-A expression. This study shows how a factor specific to late-stage neural progenitors...

... of SMC and the mitotic activity in the developing wing disc, we used BrdU immunolabeling to monitor the mitotic activity in an enhancertrap transformant line, A101, where the SMCs can be visualized. Our results indicate that SMCs arise from clusters of mitotically quiescent cells (MQC), and that the cell...
