3 important questions on Clinical research and biomedicine - Stem cell research and the law - Different kind of stem cells
What can stem cells do? (2)
- They can renew themselves whilst undifferentiated
- they can differentiate into a wide range of particular specialist cells (multi-, pluri- of totipotent)
How can stem cells be isolated?
- In the foetus
- from blood taken from the umbilical cord
- from tissues in children and adults (somatic stem cells)
- in the early embryo (embryonic stem cells)
- they are pluri- or totipotent
- from supernumerary embryo's of cell nuclear replacement
What is Cell nuclear replacement?
A technique in which the genetic material (DNA) from an egg cell is replaced with that of an adult or embryo body cell
- also cloning
