3D reconstructed volumes of µCT data of 48hpf zebrafish for three different conditions of sample mounting. (a) Lateral, dorsal and frontal view of a single 48hpf zebrafish mounted in liquid isopropanol (blue), paraffin-embedded (gray) and critical-point-dried (green). The bar graph shows the reduction in sample length (b) and volume (c) as it proceeds along the experimental pipeline shown in Fig. 1. Graphs (d) and (e) show the reduction in total sample length (c) and volume (d) plotted as a percentage of the isopropanol condition (first sample-mounting strategy). In all graphs, lines connect individual samples to show individual alteration throughout the procedure. Values indicate the mean ± standard deviation. *P < 0.05: the difference between groups was statistically significant; ns: not significant. Data were analyzed by one-way ANOVA followed by Bonferroni post-tests. N = 4 samples. Scale (X × Y): lateral view: 1600 µm × 1600 µm; dorsal view: 1500 µm × 1550 µm; frontal view: 1500 µm × 600 µm. |
