Abstract

In the 10 years that the technology to produce human embryonic stem cell lines has been available, hundreds of lines have been derived in numerous global locations. These cell lines are being used by researchers across diverse scientific fields to investigate the basic biology, clinical potential, and pharmaceutical applications of these cells and their progeny. In this fast-moving and rapidly growing field, how can we ensure that data generated by different laboratories using the same cell lines are comparable, reproducible, and consistent? One suggestion would be to ensure the quality of the "seed stock" material received and used by researchers. Because a number of laboratories worldwide provide stem cell lines to the scientific community, it seems logical to explore the harmonization of practices between distributors to establish cohesive standards and aid the global movement of stem cell lines to the research community. In the future, when these cells arrive in the clinic for therapeutic use, this consensus of "best practice" should ensure the consistency and facilitate the dissemination of these valuable materials.
