From D5, the cell counts more than doubled every two days, with a peak fold-increase at D7 in CD8+ T cell culture (3.2 times for both cancer and healthy samples) and D11 in NK cell culture (2.9 times in cancer and 2.7 times in healthy samples), followed by a gradual decline until D15 (Figure 2A1, A2). The gene discussed is CD8A; the disease is cancer.
