Nano-sized vesicles as information messengers

EXOSOME

Exosomes act as essential messengers in the body’s communication processes. Composed of various bioactive substances beneficial to the body, exosomes function as carriers, delivering these substances to other areas within the body. With a scarce presence, making up only 0.1% of active ingredients in stem cell culture media, exosomes are increasingly studied and highly regarded as ingredients in cosmetics.

Exosomes are nano-sized vesicles produced and secreted by cells, facilitating intercellular communication. Present in only 0.1% of stem cell culture media, they play a crucial role. Rich in beneficial bioactive substances like proteins, nucleic acids, and lipids, exosomes contain between 200 to 500 types of growth factors.
