Meclozine ameliorates FGF2-induced hyper ossification in larval zebrafish. (A) Representative craniofacial cartilage elements of larval zebrafish from ventral view, three-dimensional (3D) view, and single layer at seven dpf in Tg (col2a1a:EGFP) after FGF2 treatment, with or without meclozine. Scale bar indicates 100 µm. (B) Quantification of area of craniofacial cartilage, including ceratohyal (ch), hyosymplectic (h), and palatoquadrate (pq) after FGF2 treatment with or without meclozine. (C) Representative craniofacial cartilage and bone elements of larval zebrafish from ventral view, 3D view, and single layer at seven dpf in Tg (col2a1a:EGFP) stained with Alizarine red after FGF2 treatment, with or without meclozine. Scale bar indicates 100 µm. (D) Quantification of relative ossification area, including ceratohyal (ch), hyomandibular (hm), and quadrate (q) after FGF2 treatment with or without meclozine. Relative ossification area was calculated by dividing each red signal area by each green area. Data values are presented as means and standard deviation (SD). Statistical significance was analyzed by one-way ANOVA with post-hoc Tukey HSD.
