Cells from supraneural body tissues induce MCF-7 cell death. A Three images obtained from the video document. The MCF-7 cells were treated with an equal amount of SB cells. B 1 × 10⁶ MCF-7 cells were treated with various amounts of SB cells for 1 h. 1 negative control, 2 MCF-7 cell:lamprey cells 10:1, 3 MCF-7 cell:lamprey cells 5:1, 4 MCF-7 cell:lamprey cells 1:1. Cell death was examined using the Annexin-V-FITC assay kit according to the manufacturer’s instructions and analyzed with a flow cytometer
