- Stem Cells
- A stem cell is an undifferentiated cell that is able to divide to produce more stem cells or differentiate into any type of specialised cell.
- The process by which stem cells become specialised is called differentiation.
- In animal cells the ability to differentiate is lost as the animal matures.
- Plants, however, never lose this ability.
- Adult s only have stem cells in bone marrow but these can only differentiate into a few specific type of cells.
- Adult stem cells are used to cure diseases since they can specialise into the cells needed
to replace those damaged by disease.
- Scientists have experimented with extracting stem cells from early human embryos, reproducing them under particular conditions so that they differentiate into particular types of specialised cells.
