Fig. 1From: Improving immunological tumor microenvironment using electro-hyperthermia followed by dendritic cell immunotherapyApoptosis in mEHT-treated CT26 cells. One and a half million CT26 cells were heated to 42 °C for 30 min using LabEHY or a water bath (control). The apoptosis of CT26 cells after 24 h of hyperthermia treatment was analyzed using Annexin-V assay. (*, p < 0.05; n = 3)Back to article page
