To identify growth factor regulated genes, gene traps are used in embryonic stem (ES) cells. In this approach, a promoterless reporter gene (for instance encoding beta galactosidase, or beta geo) is introduced into ES cells. Selection for expression of the gene requires transcription from a cellular promoter, and consequently a mutation in a cellular gene, and the activity of the tagged gene can be followed by staining for beta galactosidase activity. Detailed description of methods used for gene trap mutagenesis may be found in Friedrich, G., and Soriano, P. (1993) and Chen, W.V., and Soriano, P. (2003). Large scale sequencing of ES cell clones was conducted and sequence tags have been deposited to NCBI's dbGSS. Sequence searches for genes that have been trapped can be performed by running a BLAST search of the dbGSS database.
