The present invention relates to a method for ex vivo photodynamic treatment of cells. A cell preparation is incubated in a first medium having 5 μM or less of a photosensitive compound. A population of cells in the cell preparation retains the photosensitive compound, for example, a salt of 2-(4,5-dibromo-6-amino-3-imino-3H-xanthen-9-yl)-benzoic acid methyl ester. The first medium is then replaced with an extrusion medium to remove the photosensitive compound. The cell preparation is then illuminated in the extrusion medium to selectively kill the population of cells retaining the photosensitive compound, thereby creating an illuminated cell preparation.
本发明涉及一种细胞体外光动力治疗方法。细胞制备物在含有 5 μM 或更少光敏化合物的第一
培养基中培养。细胞制备物中的细胞群保留光敏化合物,例如 2-(4,5-二
溴-6-
氨基-3-亚
氨基-3H-
氧杂蒽-9-基)-
苯甲酸甲酯的盐。然后用挤压
培养基取代第一种
培养基,以除去光敏化合物。然后在挤压
培养基中对细胞制备物进行光照,选择性地杀死保留光敏化合物的细胞群,从而产生光照细胞制备物。
