Microtubules regulate cardiomyocyte transversal Young’s modulus [PDF]

Proceedings of the National Academy of Sciences, 2020
The field of cardiomyocyte mechanobiology is gaining significant attention, due to accumulating evidence concerning the significant role of cellular mechanical effects on the integrated function of the heart. To date, the protein titin has been demonstrated as a major contributor to the cardiomyocytes Young’s modulus (YM).
