Dynamic cell fate plasticity and tissue reintegration drive functional adult synovial joint regeneration after complete resection - Nature Communications
Joint injury and disease are leading causes of disability, with mammalian joints exhibiting poor regenerative capacity. Here the authors showed that after loss of a whole joint, adult zebrafish regenerate de novo articular cartilage, ligament, and synovium into a complex joint organ.
