The gastrointestinal tract is one of the most sensitive organs to injury upon radiotherapeutic cancer treatments. It is simultaneously an organ system with one of the highest regenerative capacities following such insults. The presented protocol describes an efficient method to study the regenerative capacity of the intestinal epithelium.

Here, we present protocols to visualize calcium (Ca2+) responses elicited by HeLa cells infected by Shigella. By optimizing the parameters of bacterial infection and imaging with Ca2+ fluorescent probes, atypical global and local Ca2+ signals induced by bacteria over a large range of infection kinetics are characterized.

FAQs
Detection begins through cell-surface receptors and changes in cell-cell contacts. These signals indicate that the epithelial barrier has been disturbed by injury, infection, mechanical stress, or chemical cues. Once detected, the cells can shift from maintaining routine tissue organization toward coordinated activities that protect exposed surfaces and support restoration of tissue homeostasis.
Cell-cell junctions help preserve the continuity and organization of an epithelial layer. When disruption occurs, altering these junctions can help cells respond to the newly exposed or damaged region while coordinating behavior with neighboring cells. Studying these changes shows how epithelial tissues balance barrier maintenance with the remodeling needed for repair.
Migration helps epithelial cells move across exposed surfaces, providing an early way to improve coverage after disruption. Proliferation, in contrast, increases the number of cells available to restore the epithelial layer. Their coordinated activation supports barrier recovery, while examining their relative contributions can clarify how tissues respond to different forms of damage or signaling.
A response that does not resolve can shift from protective repair toward sustained tissue disturbance. Persistent signaling, altered cell behavior, or continued changes in epithelial organization may interfere with normal homeostasis. This makes epithelial response relevant to chronic disease and tumor progression, where researchers examine how normally beneficial repair programs become associated with pathological tissue states.
Researchers can examine epithelial response after injury, during infection, under mechanical stress, or following exposure to chemical signals. These conditions represent distinct challenges to barrier integrity and tissue regulation. Comparing them helps reveal which cellular reactions are shared across contexts and which responses are associated with particular environmental or biological disruptions.
Studies can investigate how epithelial tissues repair wounds, regulate inflammation, and interact with microbes. They can also examine why responses become abnormal in epithelial disorders or contribute to tumor progression. This knowledge supports research on tissue repair and infection while helping clarify the biological processes underlying diseases linked to disrupted epithelial homeostasis.
