High resolution single cell transcriptomics reveals heterogeneity of self-renewing hair follicle stem cells

Project description:Purpose: To dissect the transcriptomic profiles and unravel population-specific transcriptional heterogeneity of self renewing hair follicle stem cells in vivo Methods: We performed 10x genomics single-cell RNA sequencing (scRNA-seq) of FACS sorted CD34+/K14-H2BGFP+ hair follicle stem cells from mouse skin at mid-anagen. FACS purified CD34+/K14-H2BGFP+ single-cell suspension was processed for the barcoded single-cell 3′ cDNA libraries generation using Chromium Single Cell 3′ gel bead and library Kit v3. The final libraries were quantified using Agilent Bioanalyzer high sensitivity DNA chip and sequenced using an Illumina NextSeq-500. The raw data files were demultiplexed to generate the sample-specific FASTQ files, which were aligned to the mouse reference genome (mm10-3.0.0) using the 10x Genomics Cell Ranger pipeline (v3.1.0). The raw scRNA-seq data was processed using Cell Ranger from the 10x platform to generate an expression matrix that was further analyzed in R using the Seurat package version 3.1. Only high-quality cells that had between 200 and 5000 genes expressed and had under 10% of the UMIs mapped to mitochondrial genes were retained. Results: We obtained a total of 6736 high quality cells from two datasets for further analysis by Seurat workflow Conclusions: Obtained high quality single cell transcriptomic data to dissect molecular heterogeneity of hair follicle stem cells

Lgr6 Marks Stem Cells in the Hair Follicle that Generate all Cell Lineages of the Skin

Project description:Mammalian epidermis consists of three self-renewing compartments: the hair follicle, sebaceous gland and interfollicular epidermis. We generated knock-in alleles of murine Lgr6, a close relative to the Lgr5 stem cell gene. Lgr6 was expressed in the earliest embryonic hair placodes. In adult hair follicles, Lgr6+ cells resided in a previously uncharacterized region directly above the follicle bulge. They expressed none of the known bulge stem cell markers. Prenatal Lgr6+ cells established the hair follicle, sebaceous gland and interfollicular epidermis. Postnatally, Lgr6+ cells generated sebaceous gland and interfollicular epidermis, while contribution to hair lineages gradually diminished with age. Adult Lgr6+ cells executed long-term wound repair, including the formation of new hair follicles. We conclude that Lgr6 marks the most primitive epidermal stem cell. For the Lgr5 and Lgr6 stem cell comparison RNA was isolated from sorted GFPhi cell fractions of dorsal skin from Lgr5-EGFP-ires-CreERT2 mice and Lgr6-EGFP-ires-CreERT2, respectively (3 mice per group per sort).

Autophagy induces hair follicle stem cell activation and hair follicle regeneration by regulating glycolysis

Project description:In this study, in order to explore the role of autophagy of human hair follicle stem cells in hair growth, we explored new ideas for hair regrowth. In this study, rapamycin was used to treat hair follicle stem cells to promote autophagy, and the different expression of genes was observed by comparing with the blank control group.

Nfatc1 Orchestrates Aging in Hair Follicle Stem Cells

Project description:Mouse hair follicles undergo synchronized cycles. Cyclical regeneration and hair growth is fueled by hair follicle stem cells (HFSCs). We used ChIP-seq to unfold genome-wide chromatin landscapes of Nfatc1 and dissect the biological relevence of its upstream BMP signaling in HFSC aging. Telogen quiescent hair follicle stem cells (HFSCs) were FACS-purified for ChIP-sequcencing.
