Intravital Two-photon Imaging of Ca²⁺ signaling in Secretory Organs of Yellow Cameleon Transgenic Mice.

ABSTRACT: Intracellular calcium ([Ca²⁺]i) signaling regulates physiological functions in most cells. In secretory organs, such as the pancreas, salivary gland, and lacrimal gland (LG), [Ca²⁺]i elevation in acinar cells triggers fluid secretion, which plays vital roles in the maintenance of functional health across the life-course. It is important to understand the secretory mechanism of secretory organs, but lack of analytic systems available for living animals limits the scope of research to gain deeper insights into the precise mechanism of secretion. We established an intravital imaging system for specific cell types of secretory organs to monitor the [Ca²⁺]i changes using mouse line expressing Yellow Cameleon 3.60, a genetically encoded Ca²⁺ indicator.
