Mission Statement: The primary mission of the NIH Stem Cell Unit (SCU) is to characterize and compare pluripotent human stem cells.  We have analyzed the growth and culture conditions of all 21 human embryonic stem cell lines approved under the August 2001 Presidential Executive Order. Here we make available to the scientific community the results of our rigorous characterization of these cell lines at a more advanced level. This should allow scientists to confidently select the lines most suitable for their intended experiments.

 Selected lines have been analyzed using the Affymetrix microarray platform and are avialable now. Analysis is being completed on all lines using the Agilent microarray platform and will be avialable soon.

The Stem Cell Data Management System was developed by Amarendra S. Yavatkar, Leonard Tyson, Kory Johnson and Yang C. Fann of the Bioinformatics Section, Intramural IT and Bioinformatics Program (DIR) of the National Institute of Neurological Disorders and Stroke, NIH and Barbara Mallon, Rebecca Hamilton, Josh Chenoweth and Ron McKay of the NIH Stem Cell Unit, NIH.
