ok, we know that stem cells from an embryo can become ANY of about 200 different cells for different organs. a person that has a degenerative disease wants stem cells from any embryo to regrow tissue, for instance, to cure the disease.
but if all of us have individual and unique DNA, making us exactly who we are, how does a stem cell taken from a "stranger" embryo grow into the cells that the sick person needs, fitting his own genetic profile? i.e., would not the donor's stem cells NOT work with the recipient's genome to make his own healthy tissue?

Stem cells do not have to match a person's genetic code. Stem cells can become anything and a person will not reject stem cells like a liver or other body part that is donated. That is why stem cell research is so important because of there ability to be able to cure some diseases. Stem cells come from bunch of cells that will not be planted in a woman's uterus to become an embryo. I don't know what the big hoopla is all about when stem cell research could have the potential to save so many lives.

Stem cells, I believe, would work best for someone who needs, say a liver. The stem cells would be tested to see if they are a 'match' for the person, just like a potential donor of a liver is tested to see if they match with the recipient. The DNA in the liver is unique, but, for example, the blood type between donor and recipient must be the same (i.e. O+, AB-, etc.). A person receiving a liver made from stem cells made from an embryo that is not a genetic match to him or her must take immuno-suppressant drugs for the rest of his or her life, as the person's immune system will reject a liver that is not that person's genetic match.
However, if a person had stem cells from, say his or her umbilical cord at birth that were used to create a liver for that person, they could use that liver and not worry about immuno-suppressants, as that liver would be the same genetic match to the person.

You're right, the "stranger" stem cells would not be completely genetically compatible with the recipient (unless they came from a twin).
A recipient of stem cells would likely have to take immunosuppressants for the rest of his or her life to prevent the immune system from rejecting those cells, much like what is done with any organ transplant.

Only compatible stem cells are used for repair.

definite, I oppose it as properly. the reason i think of is via fact public help and making use of public funds demands public action. and then there is the "slippery slope" that one and all started with birth control, then abortion, then manipulations like "in vitro", cloning and something concerning destruction of embryos. So in that sense, combating at abortion aids in combating different unethical practices. you may desire to additionally comprehend, there is understanding in touch in information the technique. So scientists and church leaders have a particular criminal accountability to protest. And my church leaders like bishops do protest the practices you suggested. it may be amazing to hearken to greater regardless of the undeniable fact that. yet you will not see the coaching interior the information very lots which retains consciences uninformed. And who is going to protest in the event that they think of of it as a thank you to have babies and shop lives. It sounds effective. desire that helps.
