Why regulating stem cell-based embryo model research is important (yet controversial)

The stem cell-based embryo model (SCBEM) takes advantage of the flexibility of pluripotent stem cells (non-reproductive cells that can give rise to many different types of cells) to resemble that of embryos. While this model has helped to advance research in diseases and develop therapies or treatments, it has also sparked international debate on what regulations should be placed on this type of experimentation.
