Revealing the amazing and unique properties of stem cells, and how they can be used to regenerate tissues.
- There are three different types of stem cell: embryonic, foetal and adult.
- Stem cells have two important features: they can produce many copies of themselves, and they can differentiate into highly specialised cells.
- Stem cells could be a vital medical tool, used to create new cells.
- Salamanders can regrow limbs if they are injured, using a group of cells called blastema.
