Microscopic investigation of villi from chorionic villous sampling [PDF]

Human Reproduction, 1998
The aim of the present study was to investigate the morphology of cytogenetically normal chorionic villi from chorionic villous sampling (CVS) specimens. This information can serve as a reference for morphological investigation of cytogenetically abnormal CVS specimens.

Metabolomic Investigation of β-Thalassemia in Chorionic Villi Samples [PDF]

Journal of Clinical Medicine, 2019
Background: Beta-thalassemias are blood disorders characterized by poorly understood clinical phenotypes ranging from asymptomatic to severe anemia. Metabolic composition of the human placenta could be affected by the presence of pathological states such as β-thalassemia. The aim of our study was to describe metabolic changes in chorionic villi samples

NSUN2‐Mediated m5C Modification of TGFB1 in Trophoblasts Remodels Macrophage Function to Prevent URSA

Advanced Science, EarlyView.
NSUN2 and m5C decline in URSA villous tissues. Trophoblast Nsun2 ablation disrupts macrophage‐mediated maternal‐fetal tolerance and triggers embryo resorption. Mechanistically, NSUN2‐YBX1 axis stabilizes m5C‐modified TGFB1 mRNA to maintain TGF‐β1 secretion and M2 polarization, and restoring this signaling rescues maternal‐fetal immune tolerance to ...
