Lamellar bodies within the neuroblasts of the neural tube in the chick embryo

Summary

The occurrence is reported of lamellar, whorl-like structures in the cytoplasm of neuroblasts and in intercellular spaces within the neural tube in chick embryos at 4-day incubation. These configurations occur in the proximity of the nuclear envelope, and of the plasma membrane; within mitochondria; in the Golgi area, and within multivesicular protrusions of the cell surface. These structures are interpreted as the morphological expression of a resettlement process of lipoprotein materials, some of which are destined to be extruded from the cell during a phase of high metabolic activity.
