Multiple Imaging Modalities for Cell-Cell Communication via Calcium Mobilizations in Corneal Epithelial Cells.

Chemical indicators are used to study calcium signaling events in the context of live cell imaging. Fluo-3 AM, Fluo-4 AM, and Cal-520 AM are three commonly used fluorescent indicators derived from the calcium chelator BAPTA. Here we describe sample protocols that detail how these indicators are used in in vitro and ex vivo experiments to analyze the role of calcium mobilizations in cell-cell communication and coordinated cellular motility in the context of wound healing.
