Extended Data Fig. 7. In situ staining for the different stromal cells.

Extended Data Fig. 7

a, Immunohistochemistry of decidual serial sections stained for cytokeratin (uterine glands), CD34 (endothelial cells), ACTA2 (perivascular populations and dS1) and IGFBP1 (stromal cells and glandular secretions) (n 2 biological replicates). ACTA2 stromal cells are confined to the stromal cells of the deeper decidua spongiosa, whereas stromal cells in the decidua compacta are ACTA2. IGFBP1 stromal cells are enriched in the decidua compacta, whereas stromal cells around the glands in the decidua spongiosa are IGFBP1. Glandular secretions are IGFBP1. b, Multiplexed smFISH for a decidua parietalis section showing the two decidual layers. ACTA2, dS1 population confined to decidua spongiosa; IGBP1 and PRL, dS2 and dS3 populations confined to decidua compacta. Samples shown are from a different individual than samples shown in Fig. 4d (n 2 biological replicates). c, Multiplexed smFISH for a decidua parietalis section showing the two decidual layers. DKK1, decidual stromal marker; ACTA2, dS1 population confined to decidua spongiosa; PRL, dS3 population confined to decidua compacta (n 1 biological replicate).
