The flow sensing endothelial cell lining of blood and lymphatic vessels is essential in vertebrates. While the mechanisms are still mysterious in many regards, several critical components became apparent through molecular biology studies. In this article, we focus on PIEZO1, which forms unusual force-sensing ion channels capable of rapid transduction of force into biological effect. We describe current knowledge and emerging challenges. We suggest the idea of using computation to construct the flow sensing mechanism of endothelium to advance understanding, develop testable hypotheses and potentially design novel therapeutic strategies and synthetic flow sensing devices.
