[Ultrastructural study of the differentiation of mammary buds during the fetal life of female mice].
On mouse female fetuses, mammary gland bud development was studied ultrastructurally. This development is characterized by: - primary bud dichotomization into two secondary ductules, - lumen formation in the primary bud and in the secondary ductules. The lumen is formed by necrosis of central cells and around it cells are organized in an epithelium.
