Menstrual Bleeding, Heavy Clinical Trial
Official title:
The Role of Plasminogen Activator Inhibitor-1 (PAI-1), Tissue Plasminogen Activator (tPA), Tissue Factor Pathway Inhibitor (TFPI), and Endometrial Endothelial Cells in Uterine Hemostasis in Humans
The purpose of the study is to learn more about the role of blood clotting factor proteins and cells in menstrual (period) bleeding. The investigators are hoping to identify differences in these proteins and cells in the menstrual blood of individuals with heavy periods compared to menstruating individuals who do not have heavy periods.
The purpose of this study is to learn if human endometrial endothelial cells (HEECs) regulate human uterine hemostasis through the up and down-regulation of pro- and anti-coagulant factors in menstrual blood including PAI-1, factor XI (FXI)-PAI-1 complex, tPA, and TFPI. This study will enroll participants with heavy menstrual bleeding (HMB) and participants without HMB. Coagulation factors will be measured in menstrual blood and mRNA for these factors will be quantified from cultured HEECS from endometrial biopsies and compared between groups. ;
