Figure Lengend Snippet: a Consensus first trimester single cell data Uniform Manifold Approximation and Projection (UMAP) for clusters based on cell type ( left panel ) and feature plot for CSF2RA ( right panel ). These data were generated by the Vento-Tormo/Teichmann groups at the Wellcome Sanger Institute, Hinxton, UK and can be accessed using CZ CELLxGENE from https://maternal-fetal-interface.cellgeni.sanger.ac.uk/ (Vento-Tormo, R., Efremova, M., Botting, R.A. et al.

Arrowheads show regions of irregular villus border in the 14wpc 45,X sample. c Immunohistochemistry of CSF2RA (Colony Stimulating Factor 2 Receptor Subunit Alpha) in 46,XX, 46,XY and 45,X placenta at 14wpc at lower magnification ( left panels ) (scale bars 100 μm) and at higher magnification ( right panels ) (scale bars 50 μm). Arrowheads show regions of irregular border and diffuse CSF2RA staining in the 14wpc 45,X villus. Inset images show higher magnification of regions indicated by an asterix. d Biological process enrichment analysis for genes lower in 45,X placenta compared to 46,XY controls (bulk RNA-sequencing n=6 each group; 266 genes identified) with a differential expression cut-off of log 2 FC>0.5 and adjusted p-value <0.05.
Article Snippet: In brief, antigen retrieval was performed to unmask the epitope (Heat Induced Epitope Retrieval (HIER), Bond-max protocol F), endogenous activity was blocked with peroxidase using a Bond polymer refine kit (cat # DS9800), then incubation was undertaken with a primary rabbit polyclonal CSF2RA (GM-CSF receptor alpha) antibody for 1 hour (Origene TA323990S, 1:100 dilution, HIER1 for 30 mins).
