|Description||By 98 hpf, Meckel’s cartilage (Mk), the palatoquadrate (pq), the dentary (d), and the maxilla (mx) are visible. The dentary follows the contour of Meckel’s cartilage posterolaterally, projecting away from the cartilage ventrally. GFP-positive chondrocytes span the mandibular symphysis (sym), where cells are positioned ventrally relative to the trajectory of the main body of Meckel’s cartilage.|
