In particular, umbilical cord-derived mesenchymal stem cells have gained attention for clinical applications owing to their strong immunomodulatory properties and low immunogenicity. These cells can repair damaged tissues and enhance metabolic and cognitive function by secreting various cytokines, growth factors, and exosomes, offering potential treatment for aging-related conditions such as osteoporosis and neurodegenerative disorders.
