Abstract excerpt
Silencing and variegated transgene expression are poorly understood problems that can interfere with gene function studies in human embryonic stem cells (hESCs). We show that transgene expression (enhanced green fluorescent protein [EGFP]) from random integration sites in hESCs is affected by variegation and silencing, with only half of hESCs expressing the transgene, which is gradually lost after withdrawal of...
