Essential Cell Biology by Bruce Alberts.
All lectures are based on content from these books. Within lectures you will be given
additional materials to read including articles and up to date research. It may be useful to
bring in material from other modules and think about how it relates to cell biology. This
module is a research led topic and will be run by leading professionals in their field.
Lecture content: Understanding cell Cytoskeleton and how they move.
The diversity of cell shape, size and organisation is endless. There are lots of different types
of cells, some examples of these are:
-Sperm cells
Amoebas – move more sedately and reshape the cell itself.
Cells in the tissue that heal the skin à they can do this because the cells move to
heal themselves. All cells rely on movement to be able to do their job. Inside all these
cells is a cytoskeleton that regulates the movement.
Q: How is cell shape and movement regulated?
Cell shape and movement rely on tight regulation of intracellular mechanics and the cell's
physical interaction with its environment.
Types of cells: All cells are able to move because of their cytoskeleton.
1) Keratinocyte – this is involved in regulating the matrix environment.
In the video: the shape stays the same when it moves. How does this happen and why?
2) Amoeba cell (A common cell found in ponds)
In the video – it maintains its shape when it moves.
