Research Abstract

We developed a platform for real-time secretion analysis at the single cell resolution. The platform enabled to monitor secretion dynamics of thousand of single cells with 30-min time resolution for over 8 hours. We also demonstrated multi-parametric measurement of secretion dynamics and cellular states with 1-min time resolution. We applied our platform to inflammatory responses of immune cells and observed intercellular and intracellular heterogeneity of cytokine secretion.
