Identification of decorin and chondroitin sulfate proteoglycans in turkey skeletal muscle. 
Turkey pectoral muscles were examined at 15 through 25 d of embryonic age in order to delineate the developmental pattern of proteoglycan expression during skeletal muscle development.  Glycosaminoglycan concentration, decorin, and muscle chondroitin sulfate proteoglycan (M-CSPG) levels were measured at each developmental age.  Glycosaminoglycan levels rose during the developmental period studied, whereas decorin and M-CSPG levels were initially high at Day 15 and then decreased.  The results from this study demonstrate the presence of both decorin and M-CSPG during turkey skeletal muscle development.
