Protocol for analysis of senescent neuronal stem cells in genetic-modified embryonic mice using in utero...

Here, we present a detailed protocol for identification and analysis of senescent neuronal stem cells (NSCs) in the developing mouse embryonic neocortex using in utero electroporation. We describe the procedures of in utero electroporation and brain slide preparation. We then detail the procedures of senescence-associated β-galactosidase (SA-β-Gal) staining and immunofluorescence staining, followed by microscope imaging analysis. This combined approach can be used to study the in situ senescence of in utero electroporated embryonic brains. For complete details on the use and execution of this protocol, please refer to Zhu et al. (2021).
