Professor David Van Vactor describes the structure of the cytoskeleton, which acts as a scaffold for the cell.
Neurons, like many cells, have a very complicated architecture, but essentially the surface of the cell is a thin lipid membrane. The part of the cell that gives a cell the ability to take shape and obtain these complex structures is a structural network underneath the surface of the cell composed of proteins polymers, like 2-by-4s, steel girders, structural elements that support the cell. Unlike a scaffold that will support a house or structure, like the one surrounding us, this skeleton, the cellular skeleton, is highly dynamic and continually changes over the life of the cell.

1069. Receptor Molecules
Professor David Van Vactor describes the role of receptor molecules, which receive signals from outside the cell, passing the signal to the inside.
1065. Growth Cones (1)
Professor David Van Vactor explains how growth cones guide axons during neurodevelopment.
1063. Drosophila as a Model System
Professor David Van Vactor discusses the properties that make the fruit fly (drosophila) a powerful model system.
1067. Growth Cones (3)
Professor David Van Vactor discusses what happens during neurodevelopment when an axon reaches its final destination.
1263. What are Model Systems? (2)
Professor David Van Vactor explains that model systems are simple organisms that allow us to study and manipulate gene function and development.
1062. What are Model Systems? (1)
Professor David Van Vactor provides a simple explanation for why researchers work with model systems (model organisms).
1064. Neurodevelopment - Axon Guidance
Professor David Van Vactor describes how axons grow during neurodevelopment.
1066. Growth Cones (2)
Professor David Van Vactor discusses how growth cones read molecular 'signposts,' which help axons find the correct path.
1452. Tau Gene (MAPT)
Neurofibrillary tangles are bundles of tau proteins, which mark the tau gene (MAPT) as a strong candidate for Alzheimer’s disease.
