To evaluate and compare production of hepatocyte growth factor (HGF) from human first-trimester implantation-site decidua (decidua basalis) and nonimplantation site decidua (decidua parietalis), and hence to determine whether human trophoblast invasion in vivo is associated with increased decidual HGF production.
Controlled prospective study.
University hospital-based study.
Ten women undergoing first-trimester termination of singleton pregnancy for psychosocial reasons without preexisting medical or gynecologic diseases.
Decidual samples surgically excised and processed for paraffin-embedded immunohistochemistry and for reverse transcription-polymerase chain reaction (RT-PCR) studies.
Protein and mRNA production in decidua basalis and decidua parietalis by immunohistochemistry and RT-PCR, respectively.
No statistically significant difference was found between decidua basalis and decidua parietalis in HGF protein or mRNA production. Immunohistochemical analysis (n = 9) showed a mean score of 3.28 +/- 2.37 for decidua basalis and 3.61 +/- 2.66 for decidua parietalis. Semiquantitative analysis of HGF mRNA expression between the two sites showed no statistically significant difference (n = 10)
Human decidual production of HGF is not influenced by trophoblastic invasion in vivo.
