摘要
We report our application of a promoterless knockout (KO) strategy combined with Flpase- and Cre-mediated recombination to efficiently ablate gene function in hu- man embryonic stem (hES) cells. Using this strategy, we modified and deleted both alleles of BAF250a (ARID 1A), a signature component of the ATP-dependent SWI/ SNF chromatin remodeling complex BAF. This strategy should facilitate the functional studies of genes essential for hES cell self-renewal and differentiation, and be instrumental for human therapeutic applications.
