Abstract

Cervical biopsies were obtained from non pregnant patients and from pregnant at various stages of gestation and during labour. The tissues were extract with a Ca++-containing buffer, and collagenase activity was determined in these extracts using a solid phase assay in which triple helical125I-labelled collagen was cleaved. Collagenase was detected in all samples but significantly elevated activity was only present in labour at 6-8 cm cervical dilatation. This provides direct evidence for the crucial role of specific collagen degradation during cervical ripening and dilatation.
