Abstrak

The two sub units of intermediate filaments, desmin and vimentin, are found in most cells of mesenchymal origin. The content and distribution of desmin in mature skeletal muscle have been known, but for vimentin has been a subject of disagreement. The present study was aimed to clarify the presence of desmin and vimentin immunoreactivities in the skeletal muscle fibers of Kedu Cemani chickens (Gallus gallus domesticus) by immunohistochemistry methods of avidin-biotin-complexs. Samples of muscle tissues were obtained from pectorales mayor, biceps brachii, and biceps femoris of five adult Kedu Cemani chickens (Gallus gallus domesticus). Immunohistochemical staining results showed that desmin immunoreactivities were detected in Z disc of myofibers, but not vimentin. The results stimulate further exploration on characteristics of Kedu Cemani chickens, especially in terms of the distribution of other intermediate filaments and neuroendocrine cells in a variety of organs system.
