Enforced expression of Id3 , which has the capacity to inhibit many basic helix-loop-helix (bHLH) transcription factors , in human CD34(+) hematopoietic progenitor cells that have not undergone T cell receptor ( TCR ) gene rearrangements inhibits development of the transduced cells into TCR alpha beta and gamma delta cells in a fetal thymic organ culture ( FTOC ).
