Interestingly, tg epsilon26 thymocytes expressed GATA-3 and TCF-1 , but not LEF-1 and PEBP-2alpha , among T cell-specific transcription factors that are involved in early T cell development , indicating that GATA-3 and TCF-1 expressed during thymocyte development do not necessarily determine the cell fate into T cell lineage .
 ( protein: PEBP-2alpha, None) , ( protein: T cell-specific transcription factors, None) , ( protein: LEF-1, None) , ( protein: tg epsilon26, None) , ( cell type: T cell lineage, None) , ( cell type: tg epsilon26 thymocytes, None) , ( protein: TCF-1, None) , ( protein: TCF-1, None) , ( protein: GATA-3, None) , ( protein: GATA-3, None)
