Exploring the application of human UCMSCs in delivery of IL24 for HCC therapy, researchers infected UCMSCs with Ad-IL24 under the control of human telomerase reverse transcriptase (hTERT) promoter which is overexpressed in cancer cells but not in somatic cells and subsequently reported inhibition of cell growth in cell line and xenograft HCC model. The gene discussed is IL24; the disease is hepatocellular carcinoma.
