Summary
| Description |
Transmission electron microscope image of a thin section cut through the developing brain tissue (telencephalic hemisphere) of an 11.5 day mouse embryo. This higher magnification image of "Embryonic brain 80415", shows an area of the luminal surface of the telencephalon, which has a junctional complex and pinocytotic vesicles. The junctional complex is divided into three types of junctions: 1) the most apical is the tight junction, which controls and/or restricts the movement of molecules across epithelial layers and helps maintain polarity, 2) the zonula adherens and 3) the desmosome, which is a spot junction. The pinocytotic vesicles are formed from coated pits in the plasma membrane and are involved in endocytosis. JEOL 100CX TEM References: Marin-Padilla, M.
