Exposure windows were 0?12 and 24?36 hpf. Exposed fish (n = 8) were compared to a DMSO control (n = 8, final concentration 0.1%). (A) Expression of fgfr s showing differential expression in fgfr1a, fgfr1b, fgfr2 and fgfr4. (B) Expression of genes involved in bone formation. (C) Genes involved in cartilage formation. From col9a1b one outlier (p < 0.01 in Grubbs? test) was removed. (D) Neural crest cell marker genes. All data are presented as box plots, with median represented by a line within the box; interquartile ranges by the boxes, 5?95 confidence intervals by whiskers and means indicated by ?+? symbol. All the data were analyzed using a Kruskal?Wallis test followed by a Dunn?s multiple comparison test. Asterisks indicate significant differences; ?p < 0.05, ??p < 0.01, ???p < 0.001.
