WebWhen the myotubes cultured in BDM-containing media were transferred to control media, sarcomeric structures were formed in 2-3 days, suggesting that the inhibitory effect of BDM on myotubes is reversible. These results suggest that actin-myosin interaction plays a critical role in the early process of myofibrillogenesis. Publication types WebNov 22, 2024 · As the central protein of muscle, myosin accounts for 50–60% of myofibrillar proteins and determines the structure, properties, and function of myofibrils [ 11 ]. Meanwhile, myosin heavy chain (MYH) isoforms are the most commonly used markers for the characterization of myotubes.

WebMyotubes show a particular positivity for actin and myosin, and M-cadherin, an adhesion molecule characteristic, as known, of satellite cells, also seems to be involved in their assembling. Rare apoptotic patterns, as evidenced by the TUNEL technique, appear during myoblast maturation. Publication types Research Support, Non-U.S. Gov't WebThe development of new, viable, and functional engineered tissue is a complex and challenging task.

WebApr 12, 2024 · The myotubes, myofibrils, and sarcomeres were observed under an inverted microscope, fluorescence microscope, and scanning electron microscope. Adipogenesis was evaluated by protein expression of the peroxisome proliferator-activated receptor γ, and oil droplet accumulation was determined by fluorescence microscopy with Nile Red stain. WebAt the non-permissive temperature of 41.5 degrees C, multinucleated myotubes readily formed in ts jun-1-infected myoblast cultures and expressed muscle-specific proteins detectable by immunofluorescent staining. These myotubes also showed strong immunofluorescent staining for Gag-Jun in the cell nuclei.
