The stories of research involving human embryonic stem cells and the policy governing that work are intertwined and stretch back into the mid-1970s. Shortly after the Supreme Court ruling in Roe v.

The position taken by President Bush both limited advances in regenerative medicine and ignored ethical guidelines. And since 2009, the Obama administration has conducted a meticulous and thorough analysis of the ethical issues inherent to human embryonic stem cell research, resulting in many lines being opened back up for research and new federal funding flowing.
