Molecular puzzle reveals unknown stages of fetal development

By applying gene analysis to individual cells from early mouse embryos, researchers at Karolinska Institutet in Sweden have discovered previously unknown cellular stages of fetal development from fertilised egg to living ...

Turning stem cells into bone with nanoclay-reinforced hydrogel

Assistant Professor Alireza Dolatshahi-Pirouz and colleagues have developed a hydrogel that combines synthetic materials with living cells, and can turn stem cells into bone without adding external growth or differentiation ...

Artificial lung cancer tissue could help find new drug treatments

A 3-D hydrogel created by researchers in U of T Engineering Professor Molly Shoichet's lab is helping University of Ottawa researchers to quickly screen hundreds of potential drugs for their ability to fight highly invasive ...

What happens to magnetic nanoparticles in cells?

Although magnetic nanoparticles are being used more and more in cell imaging and tissue bioengineering, what happens to them within stem cells in the long term remained undocumented. Researchers from CNRS, the Sorbonne Université, ...

Chimpanzee 'mini-brains' hint at secrets of human evolution

At some point during human evolution, a handful of genetic changes triggered a dramatic threefold expansion of the brain's neocortex, the wrinkly outermost layer of brain tissue responsible for everything from language to ...

Cultivating 4-D tissues—the self-curving cornea

Scientists at Newcastle University have developed a biological system which lets cells form a desired shape by moulding their surrounding material—in the first instance creating a self-curving cornea.
