Effects of DC-CIK on the LCSC cycle and apoptosis. a-d flow cytometry analysis of the cell cycle: a LCSC control group; b LCSCs co-cultured with half density of DC-CIK cells for 24 h; c LCSCs co-cultured with the same density of DC-CIK cells for 24 h; d LCSCs co-cultured with the same density of DC-CIK cells for 48 h. e-h flow cytometry analysis of cell apoptosis measured by Annexin V-FITC antibody staining. e LCSC control group; f LCSCs co-cultured with half density of DC-CIK cells for 24 h; g LCSCs co-cultured with the same density of DC-CIK cells for 24 h; h LCSCs co-cultured with the same density of DC-CIK cell for 48 h
