Enzyme-linked immunosorbant assay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR) were used to detect VEGF protein and mRNA levels in decidua.Results In all three groups, only the VEGF121 amplification product of 452 bp was visualized. The mRNA and protein levels of VEGF showed no significant differences among the three groups ( P ＞ 0.05).Conclusion In humans, early decidua VEGF121 mRNA is the main isoform. The action of mifepristone plus misoprostol on blood vessels in human decidua may be medicated by some factors other than VEGF.展开更多
