WebFeb 1, 2024 · We hypothesized that the absence of a dystrophin-actin linkage would adversely affect myofibril and cardiomyocyte structure and function. Cardiomyocyte maturation was driven by culturing long-term (80-100 days) on a nanopatterned surface, which resulted in hiPSC-CMs with adult-like dimensions and aligned myofibrils. WebFluorescent immunodetection of dystrophin was done, but the negative of the original image is shown for clarity. Most of the myofiber profiles are dystrophin-negative and can be seen due to the presence of some background, while others show an immunolabeling in their periphery, corresponding to the normal location of dystrophin.
