Here is another interesting article that talks about how some new research in stem cells and how stem cells were able to prevent tumors. Until recently, people had wondered that because stem cells are undifferentiated, they might lead to tumor formation. But a recent study done showed that when both mice and human embryonic stem cells were placed in a microcapsule made of alginate (which is made from seaweed); they actually prevented tumors from forming. They showed this by placing the stem cells (which were in a capsule) into lab animals. At the same time the research group also showed that the differentiating of the stem cells is not stopped by them being encapsulated. All of this was good news for those in Australia, because it helps get rid of some bumps that might be in the way of the new human embryo cloning legislation that just passed very recently in Australia.
