Uterine microcirculation pathways (null)

Uterine microcirculation pathways refer to the intricate network of small blood vessels within the uterus—arterioles, capillaries, and venules—and the cellular and molecular systems regulating their function. These pathways are crucial for delivering oxygen and nutrients, removing waste, and enabling key processes such as cyclic tissue remodeling, embryo implantation, and maintenance of pregnancy. Vascular remodeling in the uterus, particularly around implantation and during pregnancy, involves coordinated dilation and reorganization of vessels including spiral arterioles—regulated by endothelial cells, vascular smooth muscle cells, and pericytes—under the influence of signals such as nitric oxide, prostaglandins, and endothelins. Dysregulation leads to disease states like dysmenorrhea, infertility, endometriosis, and preeclampsia, with contributing mechanisms such as impaired vasodilation, excessive vasoconstriction, or abnormal angiogenesis
