Decidualisation of cervical stromal cells

Control of cervical function is poorly understood. The major structural component of the cervix is collagen and peri-partum cervical changes are largely due to the action of collagenase, either released by resident cells or derived from an influx of neutrophils. More importantly, the cell type that initiates the changes in the cervix is unknown although the resident fibroblast is a possible contender. Little is known about the state of the cervical fibroblast during pregnancy. Decidualisation of the endometrium is essential for implantation and pregnancy. In man, pre-decidual and decidual transformation of endometrial stroma occurs under the influence of progesterone. Decidualisation can also be induced in vitro in endometrial fibroblast-like stromal cells where the process is also dependent on elevated intracellular cAMP levels.
