■Scientists engineer functional liver 'buds' from stem cells:
YOKOHAMA--In a groundbreaking development, Japanese scientists said they have engineered miniature liver "buds" from human induced pluripotent stem (iPS) cells and confirmed their functionality in mice, paving the way for applications in regenerative medicine.
The group, led by Hideki Taniguchi, a professor of regenerative medicine at Yokohama City University, and Takanori Takebe, a research associate in his lab, said they are the first to have engineered a human internal organ by using human iPS cells.
