The Role of Human Placental Mesenchymal Stem Cell Derived Exosomes in Wound Healing and Scar Therapy.

Exosomes are a subtype of extracellular vesicles, critical for intercellular communication. They are released from a cell via exocytosis, after which they travel through the extracellular fluid until they reach a target cell. Research in the fields of cellular medicine, regenerative and stem cell therapy continues to grow exponentially. Deciphering the biological properties of mesenchymal stem cells-exosomes as cell-free therapeutic tools is important for wound healing and cutaneous regeneration. The future is also bright for genetically engineering exosomes for targeted diagnostic and therapeutic applications.
