title: Disturbed trophoblast transition links early fetal to maternal syndrome progression in pre-eclampsia

description: Pre-eclampsia (PE) is a syndrome that affects multiple organ systems and is the most severe hypertensive disorder in pregnancy. It frequently leads to preterm delivery, maternal and fetal morbidity and mortality, and life-long complications (1). We currently lack efficient screening tools (2,3) and early therapies (4,5) to address PE. To study the initial stages of early onset PE, and identify candidate markers and pathways, we performed spatio-temporal multi-omics profiling of human PE placentae and healthy controls and validated targets in early gestation in a longitudinal clinical cohort. We used a single-nuclei RNA-seq approach combined with spatial proteo- and transcriptomics and mechanistic in vitro signalling analyses. This repository contains microscopy and ISS data used in the study. It contains the 113 TIFF files and 2 vsi files produced on a digital slide scanner (Olympus SLIDEVIEW VS200) connected to external LED source (Excelitas Technologies, X-Cite Xylis) and the MATLAB output files.
