Figure 4. Cardiomyocytes isolated from dysferlin knockout mouse hearts showed no significant change in morphology .

A,representative images of cardiomyocytes isolated from 3‐month‐old dysferlin knockout mice showed normal morphology and pattern of striation. B,the length and width of dysferlin‐deficient cardiomyocytes showed a slight trend of increases from that of wild‐type control, reflecting the hypertrophic phenotype. However, no statistical significance was established at the young age. Resting sarcomere length was not different in dysferlin knockout and wild‐type cardiomyocytes.
