To assess the potential therapeutic effect of IFNα-AF-MSCs on the inhibition of tumor cell proliferation, the IFNα-overexpressing AF-MSCs were cocultured with HeLa cells in a Transwell system, and the apoptotic population of the tumor cells was detected by flow cytometry via annexin/propidium iodide (PI) staining. Here, IFNA1 is linked to neoplasm.
