To determine the effect of insulin like growth factor Ⅱ(IGF Ⅱ) upon the maintenance of decidua in early pregnancy and its relationship with progesterone, as well as its role in medical abortion. Materials & Methods Decidua tissue was obtained from 28 women who undergoing surgical abortion and 39 for medical abortion respectively at 5~7 weeks of gestation. The extracted total RNA was reversely transcripted and amplified by PCR with specific primers (IGF Ⅱ and β actin). The products were semi quantitated by MIAS 300 system and qualitatively analyzed by southern blotting. Results The expression of IGF Ⅱ gene in decidua from surgical abortion was significantly higher than that from medical abortion (P<0.05). The average IGF Ⅱ gene transcription values were 1.54±0.79 and 0.72±0.39 respectively. The results of southern blotting proved qualitatively that the RT PCR products were IGF Ⅱ cDNA. Conclusion IGF Ⅱ plays a role in the maintenance of decidua in early pregnancy. It may act as a mediator of progestin. It’s also involved in the molecular mechanism of mifepristone.
