This deep dive covers Medical Applications of Stem Cells within Stem Cells and Cell Differentiation for GCSE Biology. Stem cell types, differentiation processes, therapeutic applications, embryonic vs adult stem cells, and ethical considerations It is section 4 of 17 in this topic. Use this deep dive to connect the idea to the wider topic before moving on to questions and flashcards.
🏥 Medical Applications of Stem Cells
Current Treatments:
- Bone Marrow Transplants: Treat blood cancers (leukemia, lymphoma) and immune disorders
- Skin Grafts: Treat severe burns using patient's own skin stem cells
- Corneal Repair: Restore vision using limbal stem cells
- Blood Stem Cell Therapy: Treat sickle cell disease and thalassemia
Potential Future Treatments:
- Diabetes: Generate insulin-producing pancreatic cells
- Parkinson's Disease: Replace damaged dopamine neurons
- Spinal Cord Injuries: Regenerate damaged nerve tissue
- Heart Disease: Repair damaged heart muscle after heart attacks
- Age-related Blindness: Replace damaged retinal cells
Practice questions for Stem Cells and Cell Differentiation
What is a stem cell?
Explain how sperm cells are adapted for their function.
Quick recall flashcards
What does 'totipotent' mean?
The highest level of potency - cells can differentiate into any cell type in the organism plus extraembryonic tissues like the placenta. Example: fertilized egg.
What is a stem cell?
An undifferentiated cell that can divide to produce more stem cells (self-renewal) or differentiate into specialized cell types.
