Macrophage-Induced Blood Vessels Guide Schwann Cell-Mediated Regeneration of Peripheral Nerves.
Bottom Line: Here we show that blood vessels direct the migrating cords of Schwann cells.Importantly, disrupting the organization of the newly formed blood vessels in vivo, either by inhibiting the angiogenic signal or by re-orienting them, compromises Schwann cell directionality resulting in defective nerve repair.This study provides important insights into how the choreography of multiple cell-types is required for the regeneration of an adult tissue.
