MCT1‐mediated bidirectional propionate transport across human placental syncytiotrophoblast layer: insights from a trophoblast stem cell‐derived barrier model

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Propionate in the fetal circulation is thought to originate from fermentation of dietary fibre by the maternal gut microbiota. However, the mechanism of transplacental transport has remained unclear. Here, we measured propionate permeability using a placental barrier model generated by differentiating human placental trophoblast ...

Physiological and anatomical determinants of placental drug transfer

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Fetal exposure to pharmaceuticals and their subsequent clearance back to the maternal circulation are governed by placental transfer. Passive diffusion down a maternal‐to‐fetal concentration gradient is the primary route of fetal drug exposure, with specific compounds undergoing transporter‐mediated transfer.

A primary cell‐based fluidic co‐culture model to investigate drug transport across the human placenta

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of a flow‐driven in vitro model of the human placental barrier designed to study transport processes during pregnancy. The model recreates key features of the maternal–fetal interface, enabling the investigation of how nutrients and therapeutic compounds cross the placental barrier under physiologically ...

TFAP2C is a key regulator of intrauterine trophoblast cell invasion and deep hemochorial placentation

open access: yesJCI Insight
Transcription factor AP-2 gamma (TFAP2C) has been identified as a key regulator of the trophoblast cell lineage and hemochorial placentation. The rat possesses deep placentation characterized by extensive intrauterine trophoblast cell invasion, which ...

Stepwise strategy for generating human trophoblast stem-like cells from embryonic stem cells reveals specific role of TFAP2C in acquiring self-renewability

open access: yesScientific Reports
Human trophoblast stem cells (TSCs) can self-renew and differentiate into major trophoblast lineages. Although TSC-like cells can be derived from both naïve and primed pluripotent stem cells (PSCs), the mechanisms governing the conversion of PSCs into a ...

A review of xenobiotic membrane transporter expression within the human placenta: Lessons gained from primary tissue and in vitro methodologies

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A summary of the current knowledge around membrane transporter expression in the most widely used in vitro models of human trophoblasts, including primary placental tissue, cancer cell lines and trophoblast stem cells, as well as the techniques to attempt to mimic the human placenta in vivo.

Transfer of paracetamol across the placenta and fetal blood–brain barriers and its safety for use in pregnancy

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Paracetamol (acetaminophen) is commonly taken during pregnancy for pain and fever. To gain a more comprehensive understanding of paracetamol's effects during pregnancy, several elements need to be examined including the transfer of paracetamol across the placenta and into the developing brain, the short‐ and long‐term effects of ...

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Preeclampsia‐derived small extracellular vesicles disrupt blood–brain barrier integrity and activate glial cells in vitro

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study assessed the impact of plasma‐derived small extracellular vesicles (sEVs) from healthy pregnant women and those diagnosed with late‐onset preeclampsia (PE) on the blood–brain barrier (BBB) integrity and glial cell response. PE patients had higher sEV concentrations than healthy controls.

Clinicopathological and molecular characterization of HPV‐associated cervical poorly cohesive carcinoma: a rare aggressive entity

open access: yesThe Journal of Pathology: Clinical Research, Volume 12, Issue 4, July 2026.
Abstract Primary signet‐ring cell carcinoma and poorly differentiated adenocarcinoma with poorly cohesive morphology in the cervix are rare conditions, and their clinicopathological features remain poorly described. This study defines primary cervical poorly differentiated adenocarcinomas meeting the diagnostic criteria for poorly cohesive carcinoma as
