BIOLOGY- Stem Cells
Terms in this set (10)
They are found in early human embryos and they have the potential to turn into any kind of cell at all.
Where are stem cells found in adults?
What can stem be grown in a lab to produce?
Stem cells from embryos and bone marrow can be grown in a lab to produce clones and made to differentiate into specialised cells to use in medicine or research.
Genetically identical cells.
What are stem cells used for?
Medicine uses adult stem cells to cure diseases. For example, stem cells transferred from the bone marrow of a healthy person can replace faulty blood cells in the patient who receives them.
What are embryonic stem cells used for?
They could be used to replace faulty cells in sick people. They could be used to make insulin-producing cells for people with diabetes and nerve cells for people paralysed by spinal injuries.
The embryo could be made to have the same genetic information as the patient. This means that the stem cells produced from it would also contain the same genes and so it wouldn't be rejected if used to replace faulty cells.
Risks in using stem cells for medicine?
Stem cells grown in the lab may become contaminated with a virus which could be passed onto the patient and so they could make them thicker.
Why are some people against stem cell research?
1. They feel that human embryos shouldn't be used for experiments since each one is a potential human life.
2. Curing patients who already exist and who are suffering is more important than the rights of the embryo.
How can stem cells produce identical plants?
1. In plants, stem cells are found in meristems (parts of plants where growth occurs.)
2. Throughout the plant's entire life, cells in the meristem tissues can differentiate into any type of plant cell.
3. These stem cells can be used to produce clones of whole plants quickly and cheaply.
4. These stem cells can be used to grow more plants of rare species.
5. Stem cells can also be used to grow crops of identical plants that have desired features for farmers.
