Piezo1-dependent regulation of pericyte proliferation by blood flow during brain vascular development
Zi et al. elucidate the developmental dynamics of brain pericytes and reveal that blood flow promotes pericyte proliferation. The effect of blood flow is dependent on the mechanosensitive ion channel Piezo1 in ECs, subsequently mediated by the EC-intrinsic Notch signaling, and it involves the activation of Notch signaling in pericytes.
