title: Differentiation and function of chorioallantoic cells in avian surrogate eggs.
abstract: Embryos of the domestic fowl have been successfully reared in turkey eggshells. The development of the Chorioallantois and its fusion to the shell membranes has been studied ultrastructurally and compared with the calcium transporting ability of normal embryos. There is no evidence of any species-specific effects in this functional association. The use of surrogate eggshells provides an interesting opportunity to study the differentiation and physiological properties of the chorioallantois.
