All of the human embryonic stem cells available to federally funded scientists under President Bush's three-year-old research policy share a previously unrecognized trait that fosters rejection by the immune systems, diminishing their potential as medical treatments, new research indicates.

Cells critical to sperm development have been grown in the lab and used to father baby mice, US researchers say. They said the development could lead to easier ways to genetically manipulate animals, and said
