In vitro fertilization does not increase the incidence of de novo copy number alterations in fetal and placental lineages

Project description:Although chromosomal instability (CIN) is a common phenomenon in cleavage-stage embryogenesis following in vitro fertilization (IVF), its rate in naturally conceived human embryos is unknown. CIN leads to mosaic embryos that contain a combination of genetically normal and abnormal cells, and is significantly higher in in vitro-produced preimplantation embryos as compared to in vivo-conceived preimplantation embryos. Even though embryos with CIN-derived complex aneuploidies may arrest between the cleavage and blastocyst stages of embryogenesis, a high number of embryos containing abnormal cells can pass this strong selection barrier. However, neither the prevalence nor extent of CIN during prenatal development and at birth, following IVF treatment, is well understood. Here we profiled the genomic landscape of fetal and placental tissues postpartum from both IVF- and naturally conceived children, to investigate the prevalence and persistence of large genetic aberrations that probably arose from IVF-related CIN. We demonstrate that CIN is not preserved at later stages of prenatal development, and that de novo numerical aberrations or large structural DNA imbalances occur at similar rates in IVF- and naturally conceived live-born neonates. Our findings affirm that human IVF treatment has no detrimental effect on the chromosomal constitution of fetal and placental lineages.

Comparison of genome-wide DNA methylation profiles of human fetal tissues conceived by in vitro fertilization and natural conception

Project description:Genome wide DNA methylation profiling of fetal tissue from elective terminations of pregnancy and multifetal pregnancy reduction. The Illumina Infinium HumanMethylation 450k BeadChip array was used to obtain DNA methylation profiles across approximately 453,093 CpGs in fetal tissue samples.

Hepatic RNA sequence in male mice offspring conceived by in-vitro Fertilization and Frozen-thawed Embryo Transfer

Project description:Our study reported an increased risk of metabolic disorders in in-vitro Fertilization and Frozen-thawed Embryo Transfer (IVF-FET) conceived offspring compared with those born after IVF-ET. To explore the underlying mechanisms of the aberrant metabolism in male offspring conceived by IVF and FET compared with natural conceived (NC), we performed the RNA-sequencing of livers from three groups. We performed GSEA analysis. The results suggested more severe alterations in the expression of genes involved in insulin resistance pathway in the FET-chow group than that in the IVF-chow group.

Sex-specific effects of in vitro fertilization on adult metabolic phenotypes and hepatic transcriptomic and proteomic pathways in mouse

Project description:Although in vitro fertilization (IVF) is associated with adverse perinatal outcomes, an increasing concern is the long-term health implications. We augmented our IVF mouse model to longitudinally investigate cardiometabolic outcomes in offspring from optimal neonatal litter sizes. We found that IVF-conceived females had higher body weight and cholesterol levels compared to naturally-conceived females, whereas IVF-conceived males had higher levels of triglycerides and insulin, and increased body fat composition. Through transcriptomics and proteomics of adult liver, we identified sexually-dimorphic dysregulation of the sterol regulatory element binding protein (SREBP) pathways that contribute to the sex-specfic phenotypes. We also found that global loss of DNA methylation in placenta was linked to higher cholesterol levels in IVF-conceived females. Our findings indicate that IVF procedures have long-lasting sex-specific effects on metabolic health of offspring and lay the foundation to utilize the placenta as a predictor of long-term outcomes.

scRNA-seq of human fetal lung explants with R-SPONDIN Inhibition and human fetal lung primary tissue

Project description:Here, we used single cell RNA-sequencing (scRNA-seq) to profile 13-week post-conception distal human fetal lung explants cultured in an air liquid interface system and treated with an LGR5 ectodomain adenovirus that inhibits R-Spondin function or control adenovirus. A third, non-infected, condition was also sequenced. We also performed scRNA-seq on distal human fetal lung tissue from an 8.4-week post-conception biological specimen. Diverse cell lineages were captured in all data sets, and include epithelium, mesenchyme, immune, neurons, and endothelium.
