This study aimed to evaluate the association between the concentration of cfDNA in the spent culture medium (SCM) and implantation rate, as well as the maternal immune system in IVF. The results showed that the concentration level of cfDNA in SCM was not associated with implantation rate, prediction of ongoing pregnancy, and maternal immune system.
Objectives This investigation aims to evaluate the association between the concentration of cell-free DNA (cfDNA) in the spent culture medium (SCM) with implantation rate and the maternal immune system in the invitro fertilization (IVF). In this study, 30 embryos were cultured and scored according to Gardner's criteria. SCM was gathered on day five from every embryo to analyze the quantity of cfDNA. The real-time PCR technique evaluated the expression level of transcription factors, including Foxp3, ROR gamma t, GATA3, and T-bet. The percentage of Th1, Th2, Th17, Treg, NK cells, and NK cells cytotoxicity was evaluated by flow cytometry. Results The concentration of cfDNA in the beta-HCG (-), beta-HCG ( +), and ongoing pregnancy groups were 20.70 +/- 9.224 ng/mu L, 27.97 +/- 7.990 ng/mu L, and 28.91 +/- 8.566 ng/mu L, respectively. The ratio of Th1/Th2 and Th17/Treg reduced significantly in pregnant women, as well as the level of NK cells and NK cytotoxicity cells fell dramatically in the ongoing pregnancy group. The expression level of ROR gamma t and T-bet declined while the expression level of Foxp3 and GATA3 increased considerably in pregnant mothers. Our investigation revealed that the concentration level of cfDNA in SCM could not be associated with implantation rate, prediction of ongoing pregnancy, and maternal immune system.
