- Stem Cells
- Embryonic Stem Cells
- Differentiation is the process by which a cell change to become specialised for it's job
- Animal cells, differentiation is lost at an early stage. Plant cells- don't ever lose this ability
- Some cells are undifferentiated- develop into different types of cells- STEM CELLS
- Found in early human embryos
- Adults have stem cells- found in bone marrow , but aren't as versatile
- Curing diseases
- Blood disease (eg. sickle cell anaemia)- bone marrow transplants
- Heart disease- beating heart muscles
- Diabetes- insulin producing cells
- One specific type- control differentiation by changing the environment they grow in
- Opinions
- For
- People who are suffering are more important than the lives of embryos
- Unwanted ones from fertility clinics are used- weren't for research, probably destroyed
- Against
- Potential human life
- Doctors and researchers should concentrate on finding other sources
- For
- Embryonic Stem Cells
