Stem cells

Transplanted "liver buds" self-organized to grow into functional organs, staving off death in mice with liver failure

Passage is expected for a bill that would help the market for research eggs to grow along with payments to donors

The California Institute for Regenerative Medicine is rethinking its rules in the wake of a recent breakthrough involving the creation of stem cell lines from a cloned human embryo

A new 3-D imaging technique shows that higher resolution is not the only desirable trait for microscopic observations

The breakthrough might set up another showdown about cloning for therapeutic purposes

The engineered organs were capable of producing one third as much urine as normal kidneys. The achievement suggests the potential for replacement kidneys grown on demand with no donor shortage or immune problems

Stem cells may transform the way doctors treat heart failure

Regrowing muscles, tendons and even organs may be possible using nature's own adhesive

To build large organs that work properly, researchers need to find a way to lace them with blood vessels

Neurodegenerative disorders devastate the brain, but doctors hope one day to replace lost cells
