Single-cell RNAseq of Tal1 knockout chimeric mouse embryos at embryonic day 8.5 of mouse development.. Single-cell RNAseq of Tal1 knockout chimeric mouse embryos at embryonic day 8.5 of mouse development.

Chimeric embryos were generated to investigate the effect of Tal1 knockout in mouse embryos by single-cell RNA-sequencing. Tal1 is an essential transcription factor for the formation of the embryonic blood. Embryo chimerism permits the analysis of the effects of Tal1 knockout without the confounding effects of the absence of embryonic blood, which results in global developmental failures. Embryos were generated by blastocyst injection of tdTomato-labelled, Tal1-/- mouse embryonic stem cells into wild type embryos. After blastocyst harvest, cells were flow-sorted before 10X Genomics library preparation and single-cell RNA-sequencing.
