Figure Lengend Snippet: Changes in the abundance and gene expression profile of leukocytes in Nodal Δ/Δ females. (A) t-SNE of all Ptprc + cells at the Nodal loxP/loxP (n=2) and Nodal Δ/Δ (n=2) maternal-fetal interface. (B) Proportion of cell types in each sample. Notably, the proportion of maternal neutrophils, non-classical monocytes and PAMM1a cells was significantly decreased in Nodal Δ/Δ females, while the proportion of M2 and PAMM2 cells was increased (FDR<0.05). (C) The number of significant differentially expressed genes (DEGs) (adjusted P-value<0.1) in all immune cell clusters at the d10.5 maternal-fetal interface between Nodal loxP/loxP and Nodal Δ/Δ females.
