ClearPolystyrene microplastics induce biochemical and metabolism changes in human placental explants
This study examined how polystyrene microplastics affect biochemical pathways and metabolism in human placental cells, with microplastics having been detected in human placental tissue. Polystyrene microplastics induced metabolic and biochemical changes in placental cells, raising concern for placental function and fetal health during pregnancy.
Maternal exposure to polystyrene microplastics alters placental metabolism in mice
Researchers exposed pregnant mice to polystyrene microplastics and examined how placental metabolism was affected. The study found significant changes in placental metabolic pathways that could help explain the fetal growth restriction previously observed in microplastic-exposed pregnancies. These findings suggest that microplastic exposure during pregnancy may interfere with the placenta's ability to support normal fetal development.
Polystyrene microplastics exposition on human placental explants induces time-dependent cytotoxicity, oxidative stress and metabolic alterations
Researchers exposed human placental tissue to polystyrene microplastics in the lab and found that the particles caused increasing cell damage over time, along with oxidative stress and disruptions to key metabolic processes including energy production and folate metabolism. Folate is critical for fetal development, so interference with its metabolism is particularly concerning. This study adds to growing evidence that microplastic contamination could affect pregnancy outcomes and fetal health.
Adverse effects of a realistic concentration of human exposure to microplastics on markers of placental barrier permeability in pregnant rats
Researchers exposed pregnant rats to polystyrene microplastics at concentrations realistic for human exposure and examined effects on the placenta. They found that the microplastics accumulated in placental tissue, caused oxidative stress, triggered cell death, and reduced the expression of proteins that maintain the placental barrier. The study provides the first evidence that realistic levels of microplastic exposure can compromise the protective barrier between mother and developing offspring.
Exposure of the human placental primary cells to nanoplastics induces cytotoxic effects, an inflammatory response and endocrine disruption
Scientists exposed human placental cells to polystyrene nanoparticles at concentrations found in human blood and observed cell death, inflammation, and disrupted hormone production, with smaller 20-nanometer particles causing more damage than larger ones. This is significant because the placenta is the critical barrier protecting developing babies, and these findings suggest nanoplastics may interfere with pregnancy hormones and placental function at real-world exposure levels.

Polystyrene microplastics internalization by term placental chorionic villi explants
Researchers exposed human placental tissue samples to polystyrene microplastics in the laboratory and found that the particles could cross the placental barrier and distribute within the tissue. Using advanced microscopy techniques, they observed microplastics penetrating the outer layer of placental villi and reaching deeper tissue structures within 72 hours. The findings raise concerns about potential fetal exposure to microplastics during pregnancy.
Maternal Exposure to Polystyrene Micro- and Nanoplastics Causes Fetal Growth Restriction in Mice
Researchers exposed pregnant mice to polystyrene micro and nanoplastics and found that exposure caused fetal growth restriction and placental abnormalities. The study observed that plastic particles accumulated in placental tissue and disrupted normal placental function. These findings raise concern that maternal exposure to plastic particles during pregnancy may interfere with fetal development.
Limited passage and functional effects of polystyrene micro- and nanoplastics in a physiologically-relevant in vitro human placental co-culture model
Researchers developed a placental co-culture model to study how polystyrene micro- and nanoplastics cross the placental barrier. The study found that smaller nanoplastics (50 nm) crossed more readily than larger particles, and while most cellular functions remained unaffected, exposure to the smallest nanoplastics caused a 17% decrease in estradiol hormone levels, suggesting potential endocrine effects.
Artificial plasticenta: how polystyrene nanoplastics affect in-vitro cultured human trophoblast cells
This lab study exposed placental cells (trophoblasts) to polystyrene nanoplastics and found signs of cell damage, metabolic stress, and structural breakdown under the microscope. The findings suggest that plastic nanoparticles could interfere with placental function during pregnancy, which raises concerns about potential effects on fetal development from everyday environmental plastic exposure.
Maternal exposure to polystyrene nanoparticles retarded fetal growth and triggered metabolic disorders of placenta and fetus in mice
Researchers exposed pregnant mice to polystyrene nanoplastics through drinking water and found that higher concentrations led to significantly reduced fetal weight. The nanoplastics caused abnormal cell structures in the placenta and disrupted metabolic processes in both placental tissue and fetal livers. The study suggests that maternal nanoplastic exposure during pregnancy can cross the placental barrier and interfere with normal fetal growth and metabolism.
Gestational exposure to polystyrene microplastics incurred placental damage in mice: Insights into metabolic and gene expression disorders
This mouse study found that when pregnant mice were exposed to tiny polystyrene microplastics (0.1 micrometers), the particles crossed the placenta and reached fetal livers and brains, causing placental damage and impaired fetal development. Larger microplastics (5 micrometers) were less able to cross the placenta, suggesting that the smallest plastic particles pose the greatest risk during pregnancy.
Enhanced toxic effects of photoaged microplastics on the trophoblast cells
Researchers investigated how light-aged polystyrene microplastics affect placental function in pregnant mice and found that aged particles caused greater harm than pristine ones. Oral exposure to microplastics starting early in pregnancy impaired fetal growth and damaged the placental tissue layer. The enhanced toxicity of aged microplastics appears to be linked to changes in their physical properties and increased lipid peroxidation in trophoblast cells.

Mechanistic toxicity assessment of differently sized and charged polystyrene nanoparticles based on human placental cells
Researchers tested how polystyrene nanoplastics of different sizes and surface charges affect human placental cells, which are critical for fetal development. Smaller nanoplastics and those with positive surface charges caused the most damage, including oxidative stress, DNA damage, and cell death. The findings suggest that nanoplastic exposure could potentially pose risks to placental function, highlighting the need for further research on these particles' effects during pregnancy.
Dual impact of microplastic exposure in a mouse model: Impaired uterine receptivity and altered maternal-offspring metabolism
Researchers exposed female mice to polystyrene microplastics and found that the particles impaired uterine receptivity, which is critical for embryo implantation, and altered metabolic profiles in both the mothers and their offspring. The microplastics disrupted gene expression related to uterine function and caused metabolic changes across multiple organs. The findings suggest that microplastic exposure could have reproductive and metabolic consequences that extend to the next generation.
