For decades, scientists have struggled to study this moment in humans because of ethical restrictions and limited access to ...

Scientists create a ‘mini-womb’ 3D model on a microfluidic chip which could lead to treatments for women affected by ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development - including the ...

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

For the first time in the brief history of stem cell research, Korean scientists are reporting they have cloned human embryonic tissue cells -- a major new step down the long road toward innovative ...

There are hundreds of cell types in the human body, each with a specific role spelled out in their DNA. In theory, all it ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...
