Vitelline and lipidic inclusions which are present in the neuroepithelial cells during chick embryo neurulation show a typical intracellular localization in the apical zone of the cell. In the same cellular zone the Golgi apparatus can be seen during the successive stages of neurulation. These patterns of inclusion and organelle polarity during chick embryo neurulation may be related to active consumption of the reserves contained in inclusions during this morphogenetic process. Such an active consumption would imply a close relationship between the vitelline and lipidic inclusions and the Golgi apparatus. On the other hand, the apical position of the Golgi apparatus in the neuroepithelial cells reveals the remarkable apicobasal polarity of these cells which remains unchanged during chick embryo neurulation.
