Division of hybrid cells. (a). The process of nuclear fusion and bipolar division in hybrid cells (40X). The fused cell is located in the bottom left corner of the picture. We have shown it at higher power in the top right corner to make it more convenient to observe. From T0 to T9, the fused cell maintained multiple nuclei. At the T12 time point, the nuclei had fused into a large and loose nucleus. In addition, the huge hybrid cells abruptly shrank to form a minimal globule at T15 before exploding into two new, large and irregular cells at T15. (a). The process of multipolar division of hybrid cells (40X). The fused cell is located in the top right corner of the picture. We have shown it at higher power in the bottom left corner so that it is more convenient to observe. This process was similar to that observed during bipolar division before cell division. At T11, the cell also shrank into a bright minimal globule before exploding into three new, large and irregular cells at T12.
