Ionizing radiation and chemotherapy deplete haematopoietic stem cells and damage the vascular niche. Here the authors show that irradiation induces SEMA3A secretion from bone marrow endothelial cells (ECs), inducing EC apoptosis via NRP1 and that NRP1 inhibition promotes vascular regeneration and R spondin 2 dependent hematopoietic regeneration.
