Skeletal muscle is a highly organized tissue composed of bundles of muscle fibers called myofibers which contain several myofibrils. Each myofiber represents a muscle cell with its basic cellular unit, the sarcomere. Bundles of myofibers form fascicles, and bundles of …

An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering. Each muscle is surrounded by a connective tissue sheath called the epimysium. Fascia, connective tissue outside the epimysium, surrounds and separates the muscles.

Access easy-to-understand explanations and practical examples on key biology topics, from cells to ecosystems. Learn at your own pace with bite-sized, verified content. a protein that forms (together with myosin) the contractile filaments of muscle cells, and is also involved in motion in other types of cells.

2021年5月19日 · Here, we report the significant progresses that have been made the last years to engineer muscle tissue-like structures, providing useful tools to investigate the behavior of resident cells. Specifically, we interest in the development of myopshere- and myobundle-based systems as well as the bioprinting constructs.

Skeletal muscle fibers are long, multinucleated cells. The membrane of the cell is the sarcolemma; the cytoplasm of the cell is the sarcoplasm. The sarcoplasmic reticulum (SR) is a form of endoplasmic reticulum.

2024年4月22日 · Here we generate a single-cell/single-nucleus transcriptomic and chromatin accessibility map of human limb skeletal muscles encompassing over 387,000 cells/nuclei from individuals aged 15 to...

2022年7月15日 · Here we review recent advances, current challenges and future perspectives to build human skeletal muscle tissue “in a dish”, focusing on the cellular constituents and on applications for in vitro disease modelling.

In this review, we summarize the methods used to construct skeletal muscle cell models, including hormone, inflammation, cachexia, genetic engineering, drug, and physicochemical models. We also analyze, compare, and evaluate the various construction and assessment methods.
