Characterization of ?vesselless?. (A). Schematic description of the ?vesselless? model and the experimental strategy. Green, vECs, endocardium and hematopoietic cells; red, cardiomyocytes. (B). Specific absence of hematovascular cells (i.e. vECs, endocardium, hematopoietic cells) in ?vesselless?. Green, vECs and endocardium; red, cardiomyocytes. Scale bars: 1?mm (top); 1?mm (middle); 50?µm (bottom). (C). qRT-PCR analysis of pan-hypoxia indicator genes in ?vesselless?. *P<0.05; ***P<0.001; n.s., not significant. Student?s t-test. n=8 (WT siblings), 8 (?vesselless?). (D). GO enrichment analysis of ?vesselless? (blue) and ?heartless? (red). The top 44 GO terms are shown. Highlighted are neural/sensory (green) and sterol (yellow)-related GOs. (E). Volcano plot representing differentially expressed genes in ?vesselless?. Shown are genes that are specifically affected in ?heartless? (red) and in ?vesselless? (blue). n=2. (F). qRT-PCR analysis of cholesterol biosynthesis genes. **P<0.01; ***P<0.001. n.s., not significant. Student?s t-test. n=8 (WT siblings), 7 (?vesselless? at 2?dpf), 8 (?vesselless? at 4.5?dpf). (G). Summary of differentially expressed genes in ?vesselless?.
