Glycosaminoglycans of temporomandibular articular discs

abstract — The glycosaminoglycans of the fibrous cartilage of temporomandibular articular discs from rat, rabbit, dog and monkey have been separated by means of cellulose acetate membrane electrophoresis on a micro scale. The total glycosaminoglycan amount present in these tissues was found to be 1.8, 1.8, 1.4 and 1.2 μg uronic acid, respectively, per mg tissue wet weight. Two major glycosaminoglycan fractions with the electrophoretic mobility of hyaluronate and dermatan sulfate were present, with the latter predominating.
