Human embryo models grown from stem cells

A research team headed by Prof. Jacob Hanna at the Weizmann Institute of Science has created complete models of human embryos from stem cells cultured in the lab—and managed to grow them outside the womb up to day 14. As ...

Scientists engineer synthetic DNA to study 'architect' genes

Researchers at New York University have created artificial Hox genes—which plan and direct where cells go to develop tissues or organs—using new synthetic DNA technology and genomic engineering in stem cells.

Researchers generate human-monkey chimeric embryos

Investigators in China and the United States have injected human stem cells into primate embryos and were able to grow chimeric embryos for a significant period of time—up to 20 days. The research, despite its ethical concerns, ...

Turning off 'junk DNA' may free stem cells to become neurons

For every cell in the body there comes a time when it must decide what it wants to do for the rest of its life. In an article published in the journal PNAS, NIH researchers report for the first time that ancient viral genes ...

Not all stem cells are created equal, study reveals

Researchers from the University of Toronto's Institute for Biomaterials and Biomedical Engineering (IBBME) and the Donnelly Centre have discovered a population of cells – dubbed to be "elite" – that play a key role in ...
