Exosomes from APCs ameliorate human skin fibroblast senescence via p53/p21 signaling pathway

Key Points

• Exosomes enhance fibroblast cellular functions, reducing cellular senescence related to aging.
• The key metric observed is the modulation of p53 and p21 pathways in skin fibroblasts.
• Analysis included fibroblast samples treated with exosomes from antigen-presenting cells (APCs).
• Implications suggest potential for targeted therapies that counteract aging in skin cells.
