Building a myofibril from its component proteins requires the interactions of many different proteins in a process whose details are not understood. Several models have been proposed to provide a framework for understanding the increasing data on new myofibrillar proteins and their localizations during muscle development.

Skeletal muscle cells, more commonly called muscle fibres, are multinucleated syncytia formed during development by fusion of mononucleated precursor cells, the myoblasts. They measure 10–100 μm in diameter and can have lengths from a few millimeters up to almost a meter.

Das Muskelfäserchen (Muskelfibrille, Myofibrille, Myofibril)
1957Ganz wie die Muskelfaser hat auch die Muskelfibrille eine doppelte Gliederung, eine axiale und eine transversale. Die transversale oder quere Gliederung (parallel mit der Querachse) wird dargestellt durch die verschiedenen von der Lichtmikroskopie her bekannten Bander und Zonen, die fur die Querstreifung aller quergestreiften Muskulatur verantwortlich ...

Elongation of cross-striated myofibrils
Biochimica et Biophysica Acta, 1956Abstract When myofibrils isolated from the indirect flight muscles of Calliphora were treated under the microscope with freshly-prepared crude suspensions of sarcosomes from the same muscles they elongated by about 4% and then contracted when treatment ceased; several cycles of elongation and contraction could be brought about. Evidence is given that

Cardiac muscle belongs to the striated types of muscle containing the same arrangements of myofilaments as skeletal muscle. However, unlike in skeletal muscle no syncytia are built but cylindrical muscle cells containing one large cube-shaped nucleus in central position are arranged end to end and join with adjacent cells at special attachment sites ...

Gelation of Turkey Breast and Thigh Myofibrils: Changes During Isolation of Myofibrils
Journal of Food Science, 1993ABSTRACT The relationship between functional properties of meat and myofibrils was examined for turkey breast and thigh by determining gel‐forming ability of proteins at each step in a myofibril isolation procedure. Physical properties of thermally induced gels (70°C for 30 min) were determined by torsional fracture analysis.

Volume changes in isolated myofibrils
Biochimica et Biophysica Acta (BBA) - Specialized Section on Biophysical Subjects, 1964Volume changes in glycerol-extracted myofibrils were studied. The effect of pH, ion content and ATP concentration on the change in volume was determined. A volume change greater than that attributed to ATP dephosphorylation was observed. The magnitude of the volume change of the entire system was 10−3 cm3 whereas that due to dephosphorylation was 10−6 ...

Binding of filamin isoforms to myofibrils
Journal of Muscle Research & Cell Motility, 2000Two filamin isoforms were purified from bovine tissues and characterized. Muscle filamin and nonmuscle filamin had different SDS gel mobilities, proteolytic digestion patterns, myofibrillar binding distributions and myofibril binding affinities. The muscle specific filamin had an apparent molecular weight of 265 kDa and bound primarily to the Z-lines ...

Preparation of myosin rods from myofibrils
Biochemical and Biophysical Research Communications, 1973Abstract A simple and fast procedure is described for producing myosin rods with a good yield. The method is based on the digestion of myofibrils by soluble papain. After purification by alcoholic precipitation and gel filtration, rod segments exhibited physical-chemical parameters identical to previously reported data.

Publisher Summary A variety of procedures are available for the preparation of myofibrils, and this chapter presents four of these that include myofibrils from fresh rabbit psoas muscle, myofibrils from glycerinated psoas muscle, myofibrils in bulk from fresh muscle, and myofibrils in bulk from stored muscle..
