When I was first taught the process of embryonic development in biology class back in high school, I was amazed by the complexity of the process. Each one of us was derived from a single cell (the result of the joining of an egg and a sperm), which then went through countless cell divisions. It amazes me that something so small is packed with so much biological potential!

Naturally, scientists set out to get to the bottom of this phenomenon. In the 1990s, people discovered how to extract these cells (called stem cells) from developing human embryos in order to study the process underlying stem cell development in research laboratories.
