Active and Passive Mechanical Deficits Precede Spinal Curvature in a Zebrafish Model of Idiopathic Scoliosis

Johnathan R. O’Hara-Smith, S. Bertrand, Julissa Ortiz-Delatorre…·Daniel T. Grimes

The paper identifies biomechanical deficits in zebrafish mutants that precede spinal curvature, linking urotensin signaling to axial tissue mechanics in scoliosis.
