Gene expression profile of cells from  Hey2 enhancer-LacZ transgenic (Tg) mouse embryos at embryonic day (E) 7.5.
We used single cell RNA sequencing (scRNA-seq) to analyze cells that activate the Hey2 enhancer in mouse embryos at E7.5. Overall design: E7.5 Hey2 enhancer-LacZ Tg mouse embryos were collected, and distal part of extraembryonic tissue and posterior half of the embryos were removed. The remaining part of the embryos were used for single-cell (sc) RNA-seq.
