The ex vivo EGFP+ or hypoxic population contains an average of 8% CD24+ cells, whereas the non-hypoxic or EGFP− population contains much higher numbers of CD24+ cells at approximately 13% (Fig. 2a, b), suggesting that the hypoxic TME favors tumor cells with the CD24−/low CSC-like characteristics. The gene discussed is CD24; the disease is neoplasm.
