We used reverse transcriptase -polymerase chain reaction to examine both fetal and term neonatal cord bloods for mRNA expression of three transcription factors implicated in T-cell activation : c-jun , c-fos , and NF kappa B ( p50 subunit ).
 ( protein: reverse transcriptase, None) , ( protein: c-fos, None) , ( protein: p50 subunit, None) , ( protein: transcription factors, None) , ( protein: NF kappa B, None) , ( protein: c-jun, None)
