Single-cell RNA-seq of embryonic day 17 (E17) mouse skin epithelial cells with or without Mettl3 knockout

We employed single-cell RNA sequencing to examine effects on steady-state RNA levels induced by METTL3 depletion in mouse skin epithelium during morphogenesis. YFP+ epidermal cells were isolated from E17 embryos with Mettl3 fl/+, Rosa16-YFP fl/+, K14Cre (Ctrl) and Mettl3 fl/fl, Rosa16-YFP fl/+, K14Cre (cKO) genotypes through FACS. Trypan blue staining indicates the ratio of living cells in each sample is >90%. 8000 single cells from each sample is processed with the Chromium™ Single Cell 3’ Library and Gel Bead Kit (V2) (10× Genomics, 120267) to prepare single-cell RNA-seq libraries, which is sequenced on Illumina NextSeq 500 sequenceras 26 × 57 × 8. Examination of transcriptome-wide steady-state RNA expression levels in Ctrl and cKO E17 epithelial cells.
