Stem cells used to create liver

Japanese experts are reporting a major medical breakthrough. they say they’ve created a functional human liver from stem cells.

This development could be a very important milestone in the field of human regenerative medicine. researchers mixed liver cells, cells from blood vessels, and cells that build connective tissue to create a mass that they say represents an early stage of liver development. However, scientists point out they are still a long way from producing a *fully* functional human liver, since the liver grown in Japan was only five millimeters long.
