PIEZO1 and lymphedema: In mouse, loss of Piezo1 reduces LvEC cell‐cell adhesion leading to defects in cellular condensation and a failure to form a ring‐like constriction (Choi et al., 2019; Nonomura et al., 2018), while PIEZO1 mutations are associated with lymphedema in humans (Fotiou et al., 2015; Lukacs et al., 2015).
