The rise of these iPS cells has reduced the need
for embryonic stem cells — which have long caused ethical concerns for some — and iPS cells now form the basis for most of today's stem cell research.
They tried hundreds of different recipes; eventually they discovered that if they mixed liver precursor cells (derived from iPS cells) with two other types of standard human cell lines known to be important
for embryonic liver development, then the cells would spontaneously form a 4 to 5 - millimeter 3D structure called a liver bud.
Now, scientists at the Technische Universität München (TUM) have characterized a small heat shock protein responsible

«The large amount of data our collaboration has generated sheds light on mechanisms that account
for embryonic losses at implantation,» said Olivier Sandra, team leader for the study at the Institut National de la Recherche Agronomique in France.
They then argue that «By creating a financial incentive
for embryonic stem cell research — an incentive that by NIH's own admission involves investments of «hundreds of millions of dollars» — and by specifying the precise means by which embryos must be destroyed in order to qualify for federal funding, the NIH necessarily and knowingly subjects embryos to a substantial risk of injury or death.»
