3 dpf sp7:EFP Alizarin red	Ventral Movie(s): 3 dpf Meckel's sp7 ventral movie
Description	By 78 hpf, the sp7 transgene demonstrates GFP-positive osteoblasts of the dentary (d) that have appeared along the anterolateral surface of Meckel’s cartilage (mouse over to see DIC image of Meckel’s cartilage), although no Alizarin red staining of bone matrix is visible at this timepoint. Expression of the transgene is also visible in ectodermal cells of the jaw epithelium (skin).
