Mesenchymal stem cell therapy for skin repair and rejuvenation

Mesenchymal stem cells (MSCs) are promising for skin repair and rejuvenation due to their regenerative, anti-inflammatory, and immunomodulatory properties. This review highlights MSCs from neonatal sources like the placenta and umbilical cord for their availability and scalability. MSCs aid skin repair through paracrine mechanisms, enhancing collagen production, reducing inflammation, and promoting cell growth. Clinical studies, including a meta-analysis of 55 trials with 2,696 patients, show MSCs' safety and efficacy in improving wound healing and skin conditions. Despite challenges like delivery optimization and reduced efficacy over time, MSC-based therapies, including MSC-derived extracellular vesicles and biomaterial-assisted delivery, show potential in regenerative and aesthetic applications.
