Abstract

Epithelium and mesenchyme are two distinctive cell types. Transitions occur between these during embryonic development of the mammal and chick. The chick embryo was used as a model system to study the cellular and molecular characteristics defining an epithelium and mesenchymal cell. A procedure was established to prepare serial sections of chick embryos for light microscopy observation. A study of this nature may indicate factors involved in bringing about such cellular transitions and contribute to our knowledge of what occurs in disease processes caused by the loss of a cell's typical morphology.
