Glycosaminoglycans of porcine uteri

Glycosaminoglycan fractions were obtained from the pronase digests of the endometrium and myometrium of porcine uteri. Their glycosaminoglycan compositions were determined by the use of specific mucopolysaccharide-degrading enzymes and nitrous acid. It was found that the endometrium contained chondroitin sulfates, dermatan sulfate and heparan sulfate and a smaller amount of hyaluronic acid, whereas hyaluronic acid and dermatan sulfate were the major glycosaminoglycans in the myometrium.
