    Extended Data Fig. 1 Detailed sampling of BP with PV and CAM.

    a , Sequential representative images showing the detailed sampling of the BP and PV from the placenta. b , Sequential representative images showing the detailed sampling of the CAM from the placenta.

    Extended Data Fig. 2 Immunophenotyping of nonimmune cells in the BP with PV using flow cytometry.

    a , Main gate used to identify nonimmune cells. Representative flow cytometry histograms from single antibody staining showing the presence of nonimmune cell populations in the BP with PV (BP + PV). b , Stromal cells (CD10 + cells, CD29 + cells and Vimentin + cells). c , Epithelial cells (CD326 + cells). d , Trophoblast cells (CK7 + cells). e , Hematopoietic stem cells (CD34 + cells). f , Endothelial cells (CD31 + cells). Pink histograms represent staining with indicated markers, and gray histograms represent negative controls. SSC-A, side scatter area; FSC-A, forward scatter area; Comp., compensation.
