Why do I need to provide information regarding the origin of starting cells?

ESCRO is charged with maintaining a database of information regarding the origin, function, and handling of hESCs at the University of Washington.  Please provide the basis for the selection of donors (inclusion and exclusion criteria) and rationale for conducting research with particular genotypes.  Such justification helps ensure that vulnerable populations are not enlisted for research without scientific justification and without the promise that these populations will benefit from research in the future. Please comment on how you anticipate donor populations might someday benefit from the research, if applicable.
