Relaxin and estrogen are secreted by the ovary during the second half of pregnancy in rats and mice. Relaxin promotes marked growth of the lower reproductive tract in both species. Relaxin promotes accumulation of epithelial and stromal cells in the cervix and vagina by both stimulating cell proliferation and inhibiting apoptosis. Estrogen acting through estrogen receptor alpha (ERα) plays an essential permissive role in relaxin's actions. A fundamental step toward understanding the actions of relaxin and estrogen is to identify the tissue compartments that initiate their effects. Limited studies using either antibodies to human relaxin receptor (LGR7, RXFP1) or an IRES‐LacZ reporter cassette in the LGR7 gene revealed relaxin receptors in subepithelial stroma cells and smooth muscle cells but not in epithelial cells in rodent vaginal and/or cervical tissues. ERα has been reported in both stromal and epithelial compartments in the rodent reproductive tract. This chapter describes ongoing studies that use relaxin bioactivity as a means of identifying the tissue compartment(s) that initiates the actions of relaxin and estrogen on the lower reproductive tract. Specifically, a tissue separation–recombination methodology in combination with LGR7 knockout mice was initially used to obtain functional evidence that stromal LGR7 is both necessary and sufficient to promote proliferation and inhibit apoptosis in both stromal and epithelial cells in mouse cervix and vagina. The tissue separation–recombination method is currently being used in conjunction with ERα knockout mice to determine if the obligatory permissive effect of estrogen on relaxin‐induced cell proliferation occurs through stromal and/or epithelial ERα.
