- Stem Cells
- What are Stem Cells?
- Undifferentiated cells that can specialise to be any type of cell
- They are found in human embryos.
- They are found in adult bone marrow.
- This type of stem cell cannot turn into any type of cell but only certain ones.
- What can Stem Cells be used for?
- Adult stem cells are used to treat diseases.
- Stem cells from a healthy person are used to replace faulty blood cells in another person.
- Embryonic stem cells can be used to replace faulty cells in sick people.
- They could be used to make insulin-producing cells for diabetics
- They could be used to make nerve cells for people that have been paralysed.
- Embryos can be used in Therapeutic cloning
- This means that they can be made to have the same genetic cloning of the patient
- So the stem cells have the same genes as the patient so are less likely to be rejected
- This means that they can be made to have the same genetic cloning of the patient
- Adult stem cells are used to treat diseases.
- What are the negatives to using Stem Cells?
- People think that using embryonic stem cells is unethical because it could be a human life.
- Others think that it is fine as the embryos would be destroyed anyway.
- Stem cells grown in a lab could be contaminated with a disease and this could get transferred to the patient
- People think that using embryonic stem cells is unethical because it could be a human life.
- Stem cells in Plants
- Stem cells are found in plant meristems
- Cells in the plant meristem can differentiate at any point in the plant's life
- Plant stem cells can be used to make clones of that plant.
- This can be done quickly and cheaply.
- It is used to make clones of rare plants to stop them being wiped out.
- It is also used to make clones of plants that have desired features like disease resistance.
