Chicken embryonic images showing heart morphology and the banding procedure in chick embryos at Hamburger-Hamilton stage 18 (HH18). A: microscopic image of a normal chicken embryo showing its heart and part of its circulation. VEN, ventricle; OFT, outflow tract; AOS, aortic sac; DA, dorsal aorta. Scale bar = 1 mm. B: OTF banding (OTB) in a HH18 heart showing the suture around the heart OFT. Scale bar = 1 mm. C: longitudinal tomographic section of the chick heart OFT after OTB at HH18 imaged with optical coherence tomography (OCT). Scale bar = 250 μm.
