title: Human cervical connective tissue and its reaction to prostaglandin E2.
abstract: A survey of connective tissue in general and human cervical connective in particular is presented. It is concluded that about 90% of the human cervix consists of fibrous connective tissue which, according to the composition of the collagen and the proteoglycans, is very similar to that in skin and sclera. The high activity of collagenase probably gives the cervical connective tissue from pregnant women its potential to ripen following prostaglandin treatment. Electron microscopical examination has revealed an increased amount of amorphous substance after such treatment. This may be caused partly by degraded collagen fibers and partly by newly synthesized proteoglycans.
