In this jar, hope for many who need a transplant.

In a Boston laboratory, a rat kidney has been stripped of its cells, leaving just this white scaffold.

Then the organ was reseeded with fresh cells and put into another rat. It filtered the animal’s blood and produced urine.

The results are promising but human trials are still a long way off.
