Exosomes are packets of cellular waste filled with genes (DNA, RNA), proteins and lipids that
are disposed out of the cells. They are involved in cell communication, function, and
regeneration. They can be engineered to target specific tissues with minimal immune
response as they are natural materials, even if synthetically developed or modified, therefore
are highly biocompatible.
They have been used in different fields of medicine especially oncology.
Exosomes have been shown to carry a key signalling pathway for hair morphogenesis and
regeneration. They can originate from mesenchymal stem cell, 0-to 5-month-old human
newborn foreskin stem cells, bone marrow, adipose, and amniotic stem cell.
