The epiblast of young chick embryos of stages 4–8 (Hamburger and Hamilton) was investigated by scanning electron microscopy. On the basis of surface differentiation, two zones can be distinguished. In both zones single cilia and in addition long fibrelike connections (“connecting cords”) between two non-adjacent cells can be found. The surface structures are discussed in relation to electron microscope data in terms of their origin and biological significance.
