Photodynamic Therapy Effects of Hybrid Liposomes Including Indocyanine Green against a Xenograft Mouse Model Mice of Colorectal Cancer in vivo
Author(s): Hideaki Ichihara*, Masaki Okumura and Yoko Matsumoto
Aim: To examine the photodynamic therapy (PDT) effects of hybrid liposomes (HLs) composed of L-α-
dimyristoylphosphatidylcholine (DMPC), polyoxyethylene (25) dodecyl ether (C12 (EO) 25), and indocyanine green
(ICG) in human colorectal cancer cells (HCT116) in vitro and in vivo.
Materials and Methods: HL/ICG composed of 89 mol% DMPC, 10 mol% C12 (EO) 25, and 1 mol% ICG were
prepared by sonication. The inhibitory effects of PDT-HL/ICG in a subcutaneous xenograft mouse model of
colorectal cancer were examined in vivo.
Results: The inhibitory effects of HL/ICG irradiated with far-red light laser on the growth of HCT116 cells were
observed. A remarkable reduction in tumor weight in xenograft mouse models intravenously treated with PDT-HL/
ICG after subcutaneous inoculation .. View more»
