Abstract

Calcium is one of the most important second messengers in cells and thus involved in a variety of physiological processes. In retinal pigment epithelium (RPE), Ca2+ and its ATP-dependent signaling pathways play important roles in the retina maintenance functions. Changes in intracellular Ca2+ concentration can be measured from living cells by Ca2+ imaging. Combining these measurements with quantitative analysis of Ca2+ response properties enables studies of signaling pathways affecting RPE functions. However, robust tools for response analysis from large cell populations are lacking. We developed MATLAB-based analysis tools for single cell level Ca2+ response data recorded from large fields of intact RPE monolayers. The analysis revealed significant heterogeneity in ATP-induced Ca2+ responses inside cell populations regarding magnitude and response kinetics. Further analysis including response grouping and parameter correlations allowed us to characterize the populations at the level of single cells.
