Development of the Putative Primo Vascular System Before the Formation of Vitelline Vessels in Chick Embryos
We found threadlike structures in the vitelline membrane and its surrounding dense albumen of a chick embryo by using the Trypan blue staining technique. The threadlike structure, a putative primo vessel, had DNA bodies as revealed by DAPI staining and was developed before the formation of blood vessels.
