Receptors for the steroid hormones progesterone and estrogen are critical to myometrial transformative processes.

Support for their potential crucial roles includes: i) differential levels of myometrial expression at labor; ii) transcriptional regulation of myometrial expressed genes; iii) functional abilities to mechanistically influence steroid hormone signaling; and iv) parturition-associated hormonal control of their expression.
