... was found; however, the major collagen component was the type-I collagen. On the longitudinal sites of muscle cells, there were deep recesses and, within these, finger-like structures containing sarcomers. In these recesses and in the fingerlike structures of the myo-fascial junction, the sarcolemma...

... subjected to 3 h of coronary occlusion. In the present study, which elaborates that study, we have examined the relationship between morphological variables in serial sections of 220 myocytes within the border zone. In cells with intact sarcolemma and no chromatin changes, the fractional volume of cytoplasm...

...Matti Lehto; Martti Kvist; Toini Vieno; László Józsa The macromolecular composition of sarcolemma and endomysium was studied by classical staining methods for glycosaminoglycans and using immunological techniques for proteins. Both proteoglycans and glycosaminoglycans (heparan sulphate, dermatan...

...Harol Núñez-Durán Three portions were characterized in the sarcolemma of Purkinje cells of the goat heart. These portions, i.e., intercalated disk, internal and surface sarcolemmal portion, show specific and distinctive characteristics. The surface density of both sarcoplasmic reticulum dyads...
