Nanoparticles may cause DNA damage across a cellular barrier

(PhysOrg.com) -- Scientists have shown in the laboratory that metal nanoparticles damaged the DNA in cells on the other side of a cellular barrier. The research, by the University of Bristol, is published online this week ...

Rewinding development: A step forward for stem cell research

Scientists at the Danish Stem Cell Center, DanStem, at the University of Copenhagen have discovered that they can make embryonic stem cells regress to a stage of development where they are able to make placenta cells as well ...

Cause of oversized placentas in cloning found after two decades

One reason a technique for cloning animals often results in oversized placentas, and hence failed births, has been uncovered in mice by an all-RIKEN team. This finding will help improve the success rate of the cloning method ...

Length of pregnancy influenced by placenta structure

The nine-month pregnancy in humans is influenced by the structure of the placenta, according to new research into the evolution of reproduction in mammals which ends a 100-year mystery.

Using the placenta to understand how complex organs evolve

Considering how different they look from the outside, it might be surprising that all vertebrates – animals with a backbone – share the same, conserved set of organs. Chickens, fish, human beings – all have hearts, ...
