Resumen del Recurso
Stem Cells
Embryonic stem cells can turn into ANY type of cell
Differentiation is the process by which a cell changes to become specialised for its job
Most animal cells, the ability to differentiate is lost at a early stage
Lots of plant cells don't ever lose this ability
Some cells are undifferentiated
They can develop into different types of cells, depending of what instruction they're given
These are called 'Stem Cells'
Where are Stem cells found?
Stem cells are found in early human embryos
Embryonics stem cells
Embryonic stem cells could replace faulty cell in sick people
Adults have stem cells
E.g: Bone marrow
Ain't very versatile as embryonic stem cells
They can't turn into any cell type at all (Certain ones)
Arguments against stem cells research
Experiments on potential human life is wrong
Rights of embryos
Research into stem cells
Medical researches are exciting about the potential to turn into any kind of cells at all
Stem cell maybe able to cure diseases
Medicine already use adult stem cells to cure disease
E.G: Some blood disease (E.G: Sickle cells anaemia)
Can be treated by bone marrow transplants
Bone marrow contains stem cells
Scientist can extract stem cells from early human embryos and grow them
Researchers try to control the differentiation of the stem cells by changing the environment they grow in
Needs more research
