Abstract

The skin, as the body's largest organ, undergoes significant changes with aging, impacting its structural integrity, repair capacity, and immune function. Previous studies have highlighted the heterogeneity of skin cells, particularly fibroblasts, and their role in skin homeostasis. However, the molecular and functional dynamics of these cell populations during aging, especially in sun-protected areas, remain underexplored. This study aims to elucidate the age-related changes in skin cell populations, focusing on dermal fibroblasts, using single-cell RNA sequencing (scRNA-seq) to provide insights into the mechanisms of intrinsic skin aging.

Research summary

This study investigates the age-related changes in skin cell populations, particularly dermal fibroblasts, using single-cell RNA sequencing. The research is relevant as it explores intrinsic mechanisms of skin aging, contributing to the understanding of aging processes.
