Similar to skeletal muscle, cardiac muscle is striated and organized into sarcomeres, possessing the same banding organization as skeletal muscle (Figure 10.21). However, cardiac muscle fibers are shorter than skeletal muscle fibers and usually contain only one nucleus, which is located in the central region of the cell.

A leiomyosarcoma is a malignant smooth muscle tumor. Grossly, they appear as large, fleshy masses that are irregularly shaped with visible hemorrhage or necrosis. 3 Histologic evaluation shows cells with cigar-shaped nuclei, nuclear atypia, and numerous mitotic figures (Figure 4). Necrosis and hemorrhage can often be observed.Skeletal muscle tissue develops through the fusion of individual myoblasts, or early muscle cells. This fusion results in a characteristic multinucleated structure. Because the cells are fused and multinucleated, they form a structural syncytium. Nuclei of skeletal muscle tissue are oval-shaped and located at the periphery of the cell.Dec 11, 2020 · Intriguingly, we also identified a population of nuclei (Ckm + Col1a1 +) expressing a number of skeletal muscle-specific genes (e.g., Tnni2, Tnnt3, Ckm) as well as marker genes involved in ...
