Answer:

Due to ethical reasons. Obtaining stem cells from the embryoes would require fertilisation of the embryo in order to obtain the embryonic stem cells and the embryo may not develop into a fetus upon extraction of stem cells (I may be wrong on this).

Why type of cells in your body are created through the cell cycle and mitosis?​
anygoal [31]

Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged. Hope I helped! ^^
