Embryonic, Cells from human blastocysts, Pluripotent, Requires embryo. Artificial gametes and embryos can be defined as gametes and embryos generated by manipulation of progenitor cells or somatic cells and stem cells to derive gametes and embryos assemble to their natural state, which provides a new possible therapy for infertility, especially for those people who lack healthy gametes. If the adult stem cell is taken from the person to be treated, it will not cause rejection in the body. Stem cell type, Sources, Advantages, Disadvantages. With adult stem cells the embryo is not destroyed, so it isn't an ethical issue. The body also recognises the cells as 'different' and will reject them without the use of drugs. Embryonic stem cells are easy to extract from the embryo and can produce any type of cell, but the downside of using embryonic stem cells is that the embryo is destroyed when the cell is removed, this is an ethical issue because some people believe that embryos have a right to live. They also both may produce a cancer cell instead of a healthy one, which is a risk. So, overall both embryonic and adult stem cells replace the faulty cell with a healthy cell, so the person is well again. (Adult Stem Cells) produce only a few types of cell.(Adult Stem Cells) difficult to find and extract from tissue.(All Stem Cells) may produce cancer cells instead of healthy cells.(Embryonic Stem Cells) body recognises the cells as 'different' and will reject them without the use of drugs.(Embryonic Stem Cells) embryo destroyed when cells removed - some people think embryos have a right to live.(Adult Stem Cells) if taken from the person to be treated, will not cause rejection by the body.(Adult Stem Cells) no embryo is destroyed so not an ethical issue.(All Stem Cells) replace faulty cell with healthy cell, so the person is well again.(Embryonic Stem Cells) produce any type of cell.(Embryonic Stem Cells) easy to extract from embryo.
