Transcriptional dynamics orchestrating the development and integration of neurons born in the adult hippocampus [ds1]
To profile neurogenesis in the adult mouse hippocampus, we utilized a strategy to isolate developing cells derived from RGLs expressing the proneural gene Achaete-scute homolog 1 (Ascl1). Tamoxifen administration to young-adult Ascl1CreERT2;CAGfloxStopSun1sfGFP mice were used to induce the expression of Sun1-sfGFP in the nuclear membrane of RGLs and permanently label their progeny. This birthdating tag enabled a comprehensive analysis of the entire process encompassing neuronal differentiation, development, and functional maturation. This dataset was built using FACS-sorted nuclei obtained from dentate gyri microdissected at 1-, 2-, 4-, and 8 weeks after TAM induction (cohorts w1 through w8) Overall design: 4 samples
