Single-Cell RNA-Sequencing reveals cellular heterogeneity and trajectories of lineage specification of mammary basal epithelial cells of WT and Fgd5-depeleted mice

We report the application of Single-Cell RNA-Sequencing technology for high-throughput profiling in mammary basal epithelial cells of WT and Fgd5-depeleted mice. By obtaining basal epithelial cells isolated from mammary gland of WT and Fgd5-depeleted mice, we performed Single-Cell RNA-Sequencing of basal epithelial cells. The scRNA-Seq libraries were prepared with Single Cell 3' Reagent Kit v2 (10×Genomics) following the user guide provided. We found that FGD5 promotes mammary development by maintaining LGR5/SLPI/ID3 positive basal cell subsets.. We conclude that Single-Cell RNA-Sequencing would expedite genetic network analyses and permit the dissection of complex biologic functions. Overall design: Two samples from mammary basal epithelial cells of WT and Fgd5-depeleted mice
