3.15. Lymphatic vessels in bone support regeneration after injury

L Biswas , J Chen , J De Angelis , A Singh , C Owen-Woods , Z Ding , JM Pujol , N Kumar , F Zeng , SK Ramasamy , AP Kusumbe

In Brief: Current dogma is that lymphatic vessels are absent in bone and bone marrow. Using advanced 3D-imaging and mouse genetics, these authors show the presence of lymph vessels in bone. Moreover, they show that genotoxic stress causes lymph vessels expansion and lymphangiogenesis in bone, which in turn promotes bone and hematopoietic regeneration.Commentary: The lymphatic system maintains fluid homeostasis, removes cellular waste products and produce...
