Researchers have been working on the problem of tissue engineering for years because the payoff would be so great. The ability to construct new organs would mean that patients won't necessarily have to wait for transplants.
But growing cells in lab dishes that are three-dimensional instead of flat has proved to be incredibly tricky. One group, however, claims to have made a major breakthrough.
The solution, according to a team at the MIT-Harvard Division of Health Sciences and Technology (HST), could be as simple (but incredibly elegant) as building the equivalent of biological Legos, whose structures far more closely … Read more
