The mechanisms responsible for the maintenance of pluripotency in human embryonic stem cells, and those that drive their commitment into particular differentiation lineages, are poorly understood. In fact, even our knowledge of the phenotype of hESC is limited, because the immunological and molecular criteria presently used to define this phenotype describe(More)
The DiversiLab™ rep-PCR system was used to amplify DNA regions of 28 well-characterized Escherichia coli O104 strains to generate a digital DNA fingerprint profile for strain differentiation. E. coli O104 strains from human stools and other sources were examined. The results indicate that this system can cluster similar O104 strains rapidly.
