Expression pattern of the CCAAT/enhancer-binding proteins C/EBP-alpha, C/EBP-beta and C/EBP-delta in the human placenta.

The human trophoblast has the capacity to invade maternal tissue in a controlled fashion and to produce a wide range of hormones. The transcription factors belonging to the CCAAT/enhancer-binding protein (C/EBP) family are regulators of intracellular processes and mediators of hormone action. C/EBP binding sites have been described in the promoters of several placenta-expressed target genes.
