Suppresssion subtractive hybridization (SSH) was preformed to compare gene expression profiles of PIH patients and normal pregnancy placentas. The subtractive cDNA library of PIH placenta was set up and screedned. Differential cDNAs were cloned, and sequenced by T 7 primer methodology. One hundred and three differential cDNAs were isolated by SSH. Sequencing and BLAST analysis showed 90 inserts shared more than 95% homolog with sequences in the GenBank/EMBL database. We identified 36 putative genes including pregnancy-specific glycoprotein gene (BC005924) , serine protease inhibitor gene( BC012868) , VEGFR-1 gene( AF063657 , etc.
