Complete transposition in a chick embryo demonstrated by scanning electron microscopy

Abstract

AbstractChick embryos are frequently used as animal models when researching the developing heart. In the past, every attempt to induce complete transposition (the combination of concordant arrioventricular and discordant ventriculo-arterial connections) failed in chicks, suggesting that it might be impossible to develop a chicken modle for this malformation. We demonstrate, to the best of our knowledge, the first well-documented case of complete transpositon occourrine in the chick
