- The hearts have been grown using only stem cells, for the very first time, the New Scientist reports. As such, it mimics the processes that happen when humans hearts’ grow for the first time — except it happens in a lab, at the prompting of researchers.
- The new hearts were created using stems cells that were made by reversing human skill cells, so that they turned back to something like an embryo. Once that was done, the scientists encouraged the cells to grow into the right formation, changing their shape and then eventually forming first into the cells that help hearts beat, then into those that connect the heart up and after that into tiny ventricles.
- The techniques could eventually be used to create a full-sized heart, scientists suggest to the New Scientist. The same technique might also be used to create other parts of the human body. It has long been difficult to encourage lab-created organs to grow into the right thing — but the new research gives a new insight into how stem cells turn into the right cells.
