sept6 is required for the LR patterning of visceral organs. sept6-tMO and sMO both caused aberrant patterns of liver (B and C), liver, pancreas, and gut (F), and heart (J and K), compared with the std-MO (A, E, and I). (G) Defective LR patterning of liver, pancreas, and gut in sept6 morphants rescued by wild-type sept6 mRNA coinjection. Percentages of the defective for the indicated gene and rescued embryos were quantified and are presented in the bar charts (D, H, and L).
