NIH Approves Four More Embryonic Stem Cell Lines

Stem Cells (National Science Foundation)

BioTime Inc. in Alameda, California says it has received approval from National Institutes of Health (NIH) for adding four human embryonic stem (hES) cell lines to the Human Embryonic Stem Cell Registry. Two of the company’s hES cell lines are already listed in that registry. All of the lines were developed by Biotime’s subsidiary ES Cell International.

According to Biotime, the new cell lines — identified as ESI-035, ESI-049, ESI-051 and ESI-053 — were derived using procedures and documentation in compliance with current Good Tissue Practices and Good Manufacturing Practices. BioTime has agreed to provide the complete genome sequence to the public by the fall of 2011 to encourage development of products derived from these cell lines.

In collaboration with the California Institute of Regenerative Medicine, BioTime has supplied research grade versions of these lines to researchers throughout California, including those in the University of California system.
