Stem Cells Used To Grow Miniature Human Livers In Mice

ananyo writes "Transplanting tiny 'liver buds' constructed from human stem cells restores liver function in mice, researchers have found. Although preliminary, the results offer a potential path towards developing treatments for the thousands of patients awaiting liver transplants every year. The liver buds, approximately 4 mm across, staved off death in mice with liver failure, the researchers report this week in Nature (abstract.). The transplanted structures also took on a range of liver functions — secreting liver-specific proteins and producing human-specific metabolites. But perhaps most notably, these buds quickly hooked up with nearby blood vessels and continued to grow after transplantation."

As usual, any kind of clinical use of this stem cell stuff is "ten years away". These guys are as bad as fusion researchers.

I'm sure they'd love to try it in a human dying of liver disease. But between the FDA regs, the self-appointed Medical Ethics czars, and the malpractice ambulance-chasers there's a lot of hurdles to jump before they MIGHT be allowed to try it (let alone deploy it as a regular procedure).
