Using Stem Cells to Grow Organs
Scientists have created a functional human liver for the first time using stem cells.
Researchers in Japan took cells from blood and skin and grew them into so-called liver buds.
When they transplanted the buds into mice, the buds matured and began to perform many of the functions of regular human liver cells.
The findings suggest that organs could be grown in labs, but researchers say it could be at least 10 years before lab-made livers could be used in human patients.
