Stem Cells
Human Stem Cells
- Stem cells are UNDIFFERENTIATED cells capable of becoming other types of cells, undergoing a process known as DIFFERENTIATION.
HUMANS have TWO types of stem cells:
1. Stem cells found in early HUMAN EMBRYOS, have the potential to turn into ANY cell type.
2. ADULT STEM CELLS exist too but are limited in the types of cells they can turn into. They are commonly found in BONE MARROW and can only differentiate into different types of BLOOD CELLS (e.g. RED blood cells and WHITE blood cells).
Healing with Stem Cells
STEM CELLS can be grown in labs and differentiated into specialised cells for MEDICINE or RESEARCH.
Examples include:
- ADULT STEM CELLS can be used to treat diseases by replacing faulty BLOOD CELLS in patients.
- EMBRYONIC STEM CELLS have potential in treating a variety of conditions, including DIABETES and SPINAL INJURIES.
- THERAPEUTIC CLONING involves creating embryos with the same DNA as a patient. The embryos can be used to produce stem cells with the same genetic information as the patient, which reduces any risks of REJECTION.
Ethical Considerations
- Debate surrounds stem cell research, particularly concerning the use of human embryos.
- People AGAINST stem cell research argue about using POTENTIAL HUMAN LIVES for experiments.
- People FOR stem cell research argue that benefits for SUFFERING PATIENTS are more important than the rights of an embryo.
- Stem cell research is regulated, with some countries having bans and others allowing it under strict conditions.
Plant Stem Cells
- In plants, stem cells are found in MERISTEM TISSUE, which are on the TIPS of plant shoots and roots where growth occurs.
- Unlike adult human stem cells, plant stem cells can differentiate into ANY type of plant cell.
- These stem cells can be used to produce identical CLONES of plants.
- This technique is useful for preserving RARE SPECIES of plants and producing CROPS with desirable traits like DISEASE and INSECTICIDE RESISTANCE.
