Knockdown of hspg2 is associated with craniofacial phenotypes. a-b Random control (RC) and morphant (MO) groups were stained with Alcian blue at 5 days post fertilization (DPF) (N = 20 per group). Ceratohyal, Meckel’s cartilage, and the palatoquadrate are labeled as the abbreviations (ch), (mc), and (pq) respectively. The black box on each of the images shows the mandibular jaw joint. a’-b′ The mandibular jaw joint enclosed by the black box at 40X magnification. a’ shows a red wedge indicating the normally developed gap in the mandibular jaw joint and b′ shows two red arrows which indicate an abnormally tight proximity between the two sides of the joint. c The distance between the top of the Meckel’s cartilage and top of the ceratohyal was measured across both groups (N = 20 per group) as a readout for micrognathia. Mandibular length was normalized to the random control (RC) group. *p = 0.025
