Exosomes harvested from human skin cells can repair sun-damaged skin cells in mice.
Exosomes are membrane-wrapped packages that deliver messages between cells.
Search is on for ways to use the beneficial exosomes to treat diseases.
Human skin cells replicated in a special 3D media to form a spheroid-shaped mass.
3D exosomes increased collagen production by 30%.
Also increased skin thickness by 20% compared to untreated control mice.
5% better than treatment with bone marrow-derived mesenchymal stem cells (MSCs).
No risk of immune system rejection with exosomes.
