A method for photodynamic therapy treatment of cancerous cells and tissue is provided. The method comprises administering tumor-trophic cells expressing a luminescent protein to a subject. A photosensitizing agent is then separately administered to the subject, followed by an optional iron chelator. On the day of treatment, a luminogenic substrate corresponding to the luminescent protein is administered to the subject. The substrate reacts with the luminescent protein in the vicinity of the cancerous tissue to produce light which activates the photosensitizing agent resulting in the selective destruction of the cancerous tissue.
提供了一种用于光动力治疗癌细胞和组织的方法。该方法包括向受试者注射表达发光蛋白的肿瘤热性细胞。然后单独向受试者注射光敏剂,随后是可选的
铁螯合剂。在治疗当天,向受试者注射与发光蛋白相对应的发光底物。底物与癌组织附近的发光蛋白反应,产生激活光敏剂的光,导致选择性破坏癌组织。
