The Role of UCMSC Derived Secretome in Collagen Remodeling During Skin Photoaging Molecular Mechanisms and Therapeutic Potential
Introduction: Skin photoaging is characterized by progressive disruption of the dermal extracellular matrix, particularly an imbalance between collagen synthesis and degradation. Umbilical cord mesenchymal stem cell-derived secretome has emerged as a promising cell-free regenerative approach because it contains soluble...
