title: Stereological analysis of the ultrastructure of the early chick embryo cell types involved in sorting out.
abstract: Analysis of the aggregates obtained from the prenodal region of the chick embryo (stage 5) show the existence of three cell types which sorted out. The application of morphometrical and stereological methods show that each of these cell types has a characteristic subcellular organization which is discussed with respect to the cytometrical characteristics of embryonic cells of stage 5. This early ultrastructure of each cell type is presumably related to its state of differentiation and consequently to some of the potential morphogenetic roles.
