(Submitter supplied) Pluripotent human embryonic stem cells are studied for potential applications in regenerative cell replacement therapies because of their untransformed nature and unique capacity to self-renew and differentiate. However it is known that adaptation of hESCs occurs on prolonged culture and may be associated with the acquisition of chromosome abnormalities. We report a high resolution DNA SNP 6.0 array analysis showing copy number variation in 17 different hESC lines maintained in different laboratories. more...
