FIGURE 3. Intercalation of chondrocytes in the craniofacial skeleton. Alcian blue stained samples of (A,B) wildtype (n = 4) and (D,E) sumf1?/? zebrafish (n = 6) at 5 d.p.f. The chondrocytes of wildtype larvae (B) at 5 d.p.f. were neatly stacked (asterisk) indicating complete intercalation whereas intercalation in sumf1?/? larvae (E) was disrupted in some areas (outlined) and stacked elsewhere (red star). (C,F). At 10 d.p.f. (C&F, n = 3 per genotype), the intercalation of chondrocytes was disrupted in (F) sumf1?/? larvae (asterisk and red box) when compared to (C) wildtype (asterisk). Scalebar represents 200 ?m.
