Stochastic tug-of-war among sarcomeres mediates cardiomyocyte response to environmental stiffness

Authors Haertter D, Hauke L, Driehorst T, Nishi K, Zimmermann WH, Schmidt CF Journal BioRxiv Citation bioRxiv 2024.05.28.596183. Abstract Cardiac muscle function emerges from the coordinated contraction of sarcomeres in cardiomyocytes. Sarcomere dynamics are usually inferred from whole-cell or myofibril observations, assuming synchronized, uniform behavior. Here, we investigated how different
