Study Notes
Stem Cells
- Stem cells are undifferentiated cells that can divide to create more similar cells, some of which will develop different functions.
Types of Stem Cells
Embryonic Stem Cells
- Formed when an egg and sperm fuse to create a zygote.
- Can differentiate into any cell type in the body.
- Scientists can direct these cells to differentiate into various cell types in a lab.
- These cells have the potential to replace damaged cells in conditions like diabetes and Alzheimer's, or replace nerve cells for spinal cord injuries.
Adult Stem Cells
- Found in bone marrow, among other locations.
- Can differentiate into various cell types, including blood cells.
Meristems (Plant Stem Cells)
- Located in plant root and shoot tips.
- Can differentiate into any plant cell type during the plant's life.
- Can be used to make clones of plants, useful for preserving desirable traits (like disease resistance) or for rare plant conservation.
Therapeutic Cloning
- Involves creating an embryo with the same genetic material as a patient.
- The embryo's stem cells can be harvested and used for treatment.
Benefits of Stem Cell Research
- Potential to replace damaged or diseased body parts.
- Using unwanted embryos from fertility clinics.
- Advancement of understanding cell differentiation.
Problems of Stem Cell Research
- Limited understanding of the differentiation process.
- Stem cell removal destroys the embryo.
- Ethical and religious objections regarding interference in reproduction processes.
- Risk of contamination with viruses.
- Alternative areas of medical research may be more fiscally sound to pursue.
