WebTwo methods are used to extract ES cells: the inner cell mass, which consists of the cells that will form the embryo, must be removed to extract the ES cells. Removing this mass often results in the death of this part of the embryo, but it is vital for stem cell research. To obtain a high yield of quality ES cells, embryos must be genetically identical.
