WebStem Cells in Plants Unlike in animals, plant stem cells can be obtained easily, and without ethical objection, from meristems. They can then be used to produce clones of plants quickly and economically Plant clones can be produced in weeks at a relatively low cost for their potential value 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.
