New advances in organoids, old ethical problems
|

Scientists from Cincinnati (Ohio) have developed the most complex stomach organoids to date, using embryonic stem cells. The biology of tissues and organs is difficult to study in mammals, especially in humans. However, advances in stem cell culture have made it possible to generate tiny three-dimensional tissues in vitro, called organoids. These organ models reproduce some of the anatomical and …

Pregnant and lactating women: “therapeutic orphans”?
|
|
|
Clinical research on some drugs for pregnant and lactating women sometimes tries to stop for legal, ethical and safety reasons, when there is not enough clinical evidence to give them the desired reliability. This is because some drugs used in this population group have a potential risk of adverse effects for children. Animal experimentation is not applicable in most cases …
