Mohammad Hadi L, Stamati K, Yaghini E, MacRobert AJ, Loizidou M (2023) Treatment of 3D in vitro tumoroids of ovarian cancer using photochemical internalisation as a drug delivery method. Biomedicines 11(2):572. doi: 10.3390/biomedicines11020572 PMID: 36831108
Objective: To examine the efficacy of Photochemical internalization (PCI) using a porphyrin photosensitiser and a cytotoxin (Saporin) on ovarian cancer tumouroids, with HEY ovarian cancer cells in the central cancer compartment, and HDF fibroblast cells and HUVEC endothelial cells in the surrounding stromal compartment.
Summary: The efficacy was compared to tumouroids treated with either Saporin or PDT alone, or no treatment. PCI treatment was shown to be effective in the tumouroids (determined through viability assays and imaging) and caused a considerable decrease in the viability of cancer cells both within the central cancer mass and those which had migrated into the stroma, as well as a reduction in the cell density of surrounding HUVEC and HDF.
Usage: Saporin (PR-01, 20 nM) was carried out on complex tumouroids.
