It will happen, but not by magic, and certainly not without a great deal of funding and hard work. This article from This Is Nottingham describes parts of the path from culturing cells to being able to grow an entire liver for transplant. Scientists are currently working on an intermediary steps, including a tissue matrix for liver cells, and more advanced options for artificial livers.
