Expression profiles of miRNAs in black coat color skin and white coat color skin during the 15-day embryonic stage and 7-day postnatal stage. a Heatmap of differential miRNAs in black coat color skin. The groups 13, 14 were the biological repeat samples of black mice at embryonic day 15, and the groups 16, 17, 18 were the three biological repeat samples of black mice at postnatal day 7. b Heatmap of differential miRNAs in white coat color skin. The groups 22, 23, 24 are three biological repeat samples of white mice at embryonic day 15, and the groups 19, 20, 21 are three biological repeat samples of black mice at postnatal day 7. The “S” represents the miRNA sequencing data. c Relative expression levels of miR-233, miR-217 and miR-211 in qRT-PCR. d Relative expression levels of miR-233, miR-217 and miR-211 in RNA-seq
