Description By 55hpf, Meckel’s cartilage (Mk) and the palatoquadrate (pq), derived from the first pharyngeal arch, are becoming distinct elements, with a nascent joint (j) region apparent that is GFP-negative. Alcian blue staining of matrix is observed in these developing cartilages at this timepoint (data not shown). The retroarticular process (rap) of Meckel’s cartilage projects ventroposteriorly and the pterygoid process (ptp) of the palatoquadrate projects dorsoanteriorly. GFP-positive cells are sparse in the medial mandibular symphysis (sym).
