Single cell analysis of transcriptome and open chromatin reveals the dynamics of hair follicle stem cell aging [scRNA-Seq]

As the biggest organ of human body, skin and its appendages offer excellent experimental systems for aging studies. Skin wrinkling, hair greying and hair loss are among the most striking and observable traits of aging. However, the chronic changes and cell-to-cell variation accumulated during aging in different hair follicle lineages remain unexplored. Here we present a detailed analysis of scRNAseq and scATACseq data from young and aging animals. We found distinct cellular state changes of individual hair follicle populations. Overall design: scRNA-Seq, 3 samples
