Analysis of osteoblast differentiation, cell death, and proliferation in nr2f5 misexpression embryos. (A) The sox10:DsRed transgene (magenta) and Sp7 antibody (green) label chondrocytes and osteoblasts, respectively. Note the strong Sp7 staining in the second arch-derived branchiostegal ray bone (Br). No ectopic Sp7 staining was detected in the vicinity of the transformed Meckel’s (M) cartilage. Pq, palatoquadrate; Ptp, pterygoid process (out of view in control image). (B) Similar numbers of apoptotic cells (green) were seen in the first two arches of control and sox10:Gal4VP16; UAS:nr2f5 transgenic embryos (nr2f5 OE) at 32 hpf (Mann Whitney U, p > 0.05). Arch NCCs express sox10:DsRed (mCherry antibody staining, magenta), and nuclei were labeled with Hoechst (blue). Dashed lines indicate arch boundaries. (C) nr2f5-misexpressing embryos showed a marginally significant decrease in the number of dividing cells (pHH3+, magenta) in the first two arches relative to controls (Mann Whitney U, p < 0.05). Arch NCCs express fli1a:EGFP (GFP antibody staining, green). The number of embryos evaluated for each genotype is indicated at the bottom left. Scale bars = 20 μm.
