Adult skin homeostasis involves global reorganization of dermal lineages at different stages of the mouse hair growth cycle. Vascular endothelial cadherin (VE-cadherin encoded by Cdh5 ) expressing cells from blood and lymphatic vasculature structures are known to remodel during the adult hair cycle. Here we employ single-cell RNA-sequencing (scRNA-seq) 10x-genomics analysis of FACS-sorted VE-cadherin expressing cells marked via Cdh5-CreER genetic labeling at resting (telogen) and growth (anagen) stage of hair cycle. Our comparative analysis between the two stages uncovers a persistent Ki67 + proliferative EC population and documents changes in EC population distribution and gene expression. Global gene expression changes in all the analyzed populations revealed bioenergetic metabolic changes that may drive vascular remodeling during HF growth phase, alongside a few highly restricted cluster-specific gene expression differences. This study uncovers active cellular and molecular dynamics of adult skin endothelial lineages during hair cycle that may have broad implications in adult tissue regeneration and for understanding vascular disease. |
