Abstract

Characterizing single cell contractility in the beating heart is strongly limited by light scattering and extreme tissue dynamics. Here, we use tissue-integrated microlasers to measure contractility in live zebrafish and living myocardial slices at a depth several times deeper than multiphoton microscopy-based techniques.
