The mutant embryos at 2–4 days post-fertilization are shorter than the wild type (the statistical significance is determined using a Student's t test, p < 0.01). WebThe notochord, a specialised embryonic structure, forms immediately adjacent to the dividing foregut. In the Adriamycin mouse model of oesophageal atresia, foregut and notochord abnormalities co-exist, and the site and severity of foregut malformations closely correlate to the position and extent of the notochord defects.
