The efficient transport of blood and lymph relies on competent intraluminal valves that
ensure unidirectional fluid flow through the vessels. In the lymphatic vessels, lack of luminal
valves causes reflux of lymph and can lead to lymphedema, while dysfunction of venous
valves is associated with venous hypertension, varicose veins, and thrombosis that can lead
to edema and ulcerations. Despite their clinical importance, the mechanisms that regulate

Abstract
The efficient transport of blood and lymph relies on competent intraluminal valves that ensure unidirectional fluid flow through the vessels. In the lymphatic vessels, lack of luminal valves causes reflux of lymph and can lead to lymphedema, while dysfunction of venous valves is associated with venous hypertension, varicose veins, and thrombosis that can lead to edema and ulcerations. Despite their clinical importance, the mechanisms that regulate valve formation are poorly understood and have only recently begun to be characterized. Here, we discuss new findings regarding the development of venous and lymphatic valves that indicate the involvement of common molecular mechanisms in regulating valve formation in different vascular beds.
