To avoid the controversy of using real human embryos, scientists have recently started using stem cell models to study how humans develop in the womb. Scientists are studying embryonic failure, effect of chemicals on embryos, and how the environment affects the embryos.

The embryo models can easily be replicated and cannot grow into babies, making them an ideal choice for scientists trying to replicate and watch embryos develop. Scientists are trying to study and understand things like embryonic failure, the effect of chemicals on embryos, and how the environment affects the embryos.

Scientists are also learning more about how to control what type of tissue stem cells develop into. This can be useful in a variety of cases. Imagine if someone with liver failure can be assigned a new liver! There are also many experiments that can be conducted on non-living stem-cell-tissue that can show the effectiveness and possible harm of any new medicines.

Experts say that many members of the public have the wrong idea about these stem-cell embryos, believing that they can cause pregnancies. This is not the case, as the whole idea is to avoid the real-embryo controversy. Stem cells are going to be a massive boost in the medicine of the future.
