Scientists in Massachusetts said today they had created several colonies of human embryonic stem cells without harming the embryos from which they were derived, the latest in a series of recent advances that could speed development of stem cell-based treatments for a variety of diseases.

By MALCOLM RITTER  NEW YORK - Scientists say they have created a stem cell line from a human embryo that had stopped developing naturally, and so was considered dead. Using such embryos might ease ethical concerns about creating such cells, they suggested.
