Résumé
Distribution of myosin, tubulin and laminin immunoreactive cells in the area opaca of the young chick embryo (Stages 4-8 HH) was studied using immunofluorescence technique. For the three markers, the number of stained cells increased with the age of the blastoderm. Cells stained for tubulin and laminin, were distributed throughout the area opaca, showing no supracellular organization. On the contrary, the cells stained for myosin became organized in a ring surrounding the area pellucida. This pattern appeared at the stage 6. Such an heterogenous distribution of the markers suggests a functional diversification of the ectodermal cell monolayer forming at these early developmental stages the area opaca. This idea is also supported by the results of autoradiography for tritiated thymidin which showed that the edge cells did not synthetize DNA and consequently did not divide.
