Photodynamic therapy of cervical cancer by eradication of cervical cancer cells and cervical cancer stem cells.

This study therefore, sought to determine the effect of Photodynamic Therapy (PDT) in eradicating cervical cancer and cervical CSCs. Cervical CSCs were isolated from a cervical adenocarcinoma cell line, HeLa cells, and grown in liquid medium incubated at 37° C, 5% CO2 and 85% humidity. Increasing doses of AlPcSmix photosensitizer were administered to both the total cell population and the isolated CSCs, and irradiated using 673.2 nm diode laser. Post-irradiation cellular changes were observed using biochemical assays and microscopy to determine the response of both the total cell population and the CSCs. Results showed a dose-dependent response of both cell populations to treatment, by demonstration of significant morphologic changes, increased cytotoxicity, and decreased cell viability and proliferation. The study suggested that PDT using AlPcSmix is a very effective treatment method for the eradication of cervical cancer cells and cervical CSCs, in vitro. PMID: 31320992 [PubMed]
