3.5 dpf
Alizarin red
Description By 86 hpf, Meckel’s cartilage (Mk) has increased in size from that seen at 78 hpf. Most chondrocytes of Meckel’s cartilage now span the mediolateral width of the element, which is consistent with growth by cell intercalation between 78 hpf and 86 hpf. Alizarin red staining also reflects the appearance of the dentary (d) along the ventral aspect of the anterolateral surface of Meckel’s cartilage. The retroarticular process (rap) of Meckel’s cartilage projects ventro-posteriorly from its articulation with the palatoquadrate (pq).
