5-aminolevulinic acid-mediated photodynamic therapy of human endometriotic primary epithelial cells.

Objective: Despite progress in medicine, appropriate diagnosis and treatment of endometriosis poses a serious problem. For this reason, in in-vitro experiments were performed on a potential method of employing photodynamic therapy (PDT) of endometriosis using 5-aminolevulinic acid (ALA).

Background Data: The exogenous application of ALA induces the accumulation of protoporphyrin IX, a natural and effective photosensitizer used in photodynamic diagnosis and therapy.
