Live-cell images of cells expressing CAAX-GCaMP6s in cells neighboring an irradiated cell (IMAGE)
Caption
In this image, the cell marked with an asterisk was damaged using a focused laser, triggering apoptosis. After an initial increase in general calcium levels around the dying cell (calcium wave), a sustained increase in calcium levels was observed at the interface between the apoptotic cell and the surrounding cells (marked B and D). This new mechanism is essential for expelling the apoptotic cell and preserving the integrity of the epithelium.
