Embryonic stems cells differentiate into various tissues. Research suggests 1 point that it may be possible to replicate stem cells from mouse embryos. In the
future, human stem cells may be used to replace human tissue damaged
by diseases such are Parkinson's disease and multiple sclerosis. Why might
the use of stem cells taken from a patient to replace damaged tissues
decrease the potential risk to a patient? *
Retrieving donor stem cells from human embryos is difficult and controversial
Stem cells taken from a donor and implanted into a patient can be rejected by the
patient's immune system
Stem cells may not be able to differentiate into the correct cells and tissues needed
from the patient
Stem cells from a patient will not be destroyed by the patient's own immune system
