Skin aging is a complex, multifaceted process influenced by both intrinsic and extrinsic factors. Understanding the molecular mechanisms underlying skin aging is crucial for developing effective anti-aging strategies. Dermal stem cells play a pivotal role in maintaining skin homeostasis, but their functionality is compromised with aging. This study investigated the impact of aging on dermal stem cells and explored the potential of natural extracts in modulating their biological characteristics. Using bulk RNA barcoding and sequencing (BRB-seq), we identified differentially expressed genes (DEGs) between young and aged dermal stem cells, revealing alterations in cellular processes, including cell proliferation, ECM synthesis, and RNA splicing. We also demonstrated that a natural extract, comprising callus cells and Alpine rose leaf extracts, influenced RNA splicing in aged dermal stem cells, leading to improved dermal structure and integrity in vitro. Our findings suggest that natural extracts may exert their effects through senolytic activity and the modulation of RNA splicing, a process crucial to gene expression and cellular function. This study underscores the potential of integrating high-throughput transcriptomics in understanding skin aging, presenting new avenues for the development of innovative, sustainable, and effective anti-aging strategies.
