Quantifying the Spatiotemporal Dynamics of Engineered Cardiac Microbundles

Hiba Kobeissi, Samuel J. DePalma, Javiera Jilberto +3

Brightfield time-lapse imaging is widely used in cardiac tissue engineering, yet the absence of standardized, interpretable analytical frameworks limits reproducibility and cross-p…

SarcGraph for High-Throughput Regional Analysis of Sarcomere Organization and Contractile Function in 2D Cardiac Muscle Bundles

Saeed Mohammadzadeh, Yao-Chang Tsan, Aaron Renberg +3

Timelapse images of human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) provide rich information on cell structure and contractile function. However, it is chall…
