- Stem Cells
- Sources
- Embryonic stem cells
- Created by fertilizing egg cells with sperm and procuring developed cells
- Advantages
- Almost unlimited growth potential
- Can differentiate into any type of cell
- Less chance of accumulated mutation
- Disadvantages
- Risk of becoming tumor cells
- Probably genetically different from adult patient receiving cells
- Kills embryo
- Cord blood stem cells
- Stem-cell containing blood is acquired from new-born's umbilical cord
- Advantages
- Easily acquired and stored
- Compatible with adult tissue
- Umbilical cord is discarded afterward either way
- Does not kill baby
- Disadvantages
- Limited quantity of cells
- Limited differentiation capacity
- Adult stem cells
- Obtained from tissues such as bone marrow
- Advantages
- Less chance of becoming tumor cells
- Compatible with adult tissue
- Does not kill adult
- Disadvantages
- Only a few and are buried deep in tissues
- Less growth potential
- Limited differentiation capacity
- Embryonic stem cells
- Applications
- Can be used to treat diseases which need replacement of cells
- Leukemia
- Type of cancer
- Bone marrow produces an abnormally large amount of white blood cells
- Cure
- Adult stem cells
- Stem cells are extracted from large bone. Chemotherapy is given to kill cancer cells. Stem cells are returned and become blood cells.
- This usually cures leukemia completely.
- Stem cells are extracted from large bone. Chemotherapy is given to kill cancer cells. Stem cells are returned and become blood cells.
- Adult stem cells
- Type of cancer
- Stargardt's macular dystrophy
- Photoreceptive cells in retina degenerate.
- Cure
- Embryonic stem cells
- Retina cells derived from embryonic stem cells are injected into the eyes. The cells attach to the retina and remain, improving vision.
- More trials are necessary, but this could potentially be an official treatment to Stargardt's disease.
