Top-grade stem cells seen boosting research trials

LONDON: British scientists have made the first human embryonic stem cells of a high enough grade to use in patients and deposited them in a public stem cell bank for development in human trials by drug companies and researchers by 2014.

A team from King's College London said on Monday they were submitting two clinical-grade stem cell lines to the UK Stem Cell Bank (UKSBC), which will test and validate them before offering them to researchers.
