SR_melb writes writes to tell us that Melbourn researchers have, for the first time, managed to grow three dimensional human cells. This bypasses previous achievements of only being able to create two-dimensional constructions like skin. From the article: "Professor Wayne Morrison, from Melbourne's Bernard O'Brien Institute of Microsurgery has led the breakthrough. He says it's a world first and predicts the discovery will ultimately lead to the creation of human organs, including parts of the heart, by using the patients' own stem cells. Such a scenario, says Professor Morrison, would reduce the problem of immune rejection which is often associated with organ transplants."
