Glossary Platelet Lysate

substance from broken-down platelets, rich in growth factors

Platelet Lysate (PL) is a substance derived from the breakdown of platelets, which are small cell fragments in the blood involved in clotting. It is rich in growth factors and cytokines, making it useful in regenerative medicine and tissue repair, including treatments for hair loss and alopecia.
