  • Extracellular vesicles (EVs) are lipid-enveloped nanovesicles that facilitate intercellular communication.
  • EVs from adipose-derived stem cells and umbilical cord-derived mesenchymal stem cells (UC-MSCs) were studied in 2D and 3D skin models.
  • EVs promoted fibroblast and keratinocyte proliferation, increased epidermal thickness, and enhanced collagen IV and fibrillin 1 presence.
  • Transcriptomic, miRNA-seq, and proteomic analyses revealed gene expression changes and potential drivers of skin regeneration.
  • EVs modulate biomarkers linked to skin aging in 3D reconstructed skin models.
  • The study suggests EVs could be used in next-generation regenerative skincare products.
