Higher chromosome stability in embryonic neural stem and progenitor cells than in fibroblasts in response to acute or chronic genotoxic stress

High fidelity of genetic transmission in neural stem and progenitor cells (NSPCs) has been long time considered to be crucial for brain development and homeostasis. However, recent studies have identified recurrent DSB clusters in dividing NSPCs, which may underlie the diversity of neuronal cell types. This raised the interest in understanding how NSPCs sense and repair DSBs and how this mechanism could be altered by environmental genotoxic...
