FIELD: medicine.
SUBSTANCE: microparticles are made from a copolymer of lactic and glycolic acids containing a photosensitizer. The obtained microparticles are added to the stem cells and their co-cultivation is carried out. After this, the stem cells are introduced to the subject with the tumour, and the tumour growth zone is exposed to light irradiation at a dose sufficient to completely or partially destroy the tumour.
EFFECT: targeting effect with increased amount of the photosensitizer being transported, reducing the toxic effect of the latter on stem cells and eliminating systemic phototoxic damage.
