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.

Note: Analysis of data requires a cutoff threshold below which expression is deemed negligible. Although variations may be observed below such a threshold, conclusions should be drawn with caution. For example, when analyzing the median normalized data, a cutoff of 1 may be used although a cutoff of 10 reflects a more statistically robust expression level.
