Basal release of urokinase plasminogen activator, plasminogen activator inhibitor-1, and soluble plasminogen activator receptor from separated and cultured endometriotic and endometrial stromal and epithelial cells

This study has demonstrated the basic capacity of separated epithelial and stromal cells from all three types of tissue to release uPA, PAI-1, and suPAR without any paracrine influence, as in vivo. The higher release of PAI-1 from endometriotic stromal cells might have importance for the invasive growth.
