Tcof1 knockdown in zebrafish recapitulates TCS features. (a) RT-qPCR of rRNA transcripts (by ETS and ITS quantification) in samples from control (STD) and TRA-MO-injected 256 cell stage and 24 hpf embryos. Bars represent the mean of relative abundance and S.E.M., n=3, *P<0.05, **P<0.01 (t-test). AU: arbitrary units. (b and c) Ventral views of a typical control (b; STD-MO-injected) and a representative TCS-like (c; TRA-MO-injected) 4 dpf larvae stained with Alcian Blue. Meckel area (MA), area of the inner triangle defined by the Meckel cartilage, PQ length: length of palatoquadrate+hyosymplectic cartilages, ceratohyal length (CL): length of ceratohyal cartilage, CD: distance between ceratohyal cartilages joint and lateral fins, cranial distance (Cr): distance between the most anterior Meckel and lateral fins
