For each placental single-cell signature the average Z-score of member proteins is shown as a function of gestational age. The gene symbols corresponding to each signature are: Synciotrophoblasts (KISS1, CSH1, TFPI2, CGA, GH2, PSG3, PSG2, PSG1, HOPX, CRH, GDF15, S100P, PSG11), B cells (CD79A, CD74, RPS5), Extravillous trophoblast (AOC1, PRG2, IGF2, NOTUM, FSTL3, FLT1, EBI3, PAPPA2, HPGD, HLA-G, PAPPA, ITM2B, KRT19, SERPINE2, MFAP5, HEXB, QSOX1, TPM1, TNFSF10), Stromal 1 (TIMP1, DLK1, COL3A1, COL1A1, TGFBI, IL1RL1, COL6A2, IGFBP3, DCN, COMP, SERPINE2, COL6A1), Stromal 2 (CXCL14, EGFL6, PTGDS, APOD, TCF21, DLK1, IGFBP3, COL3A1, PLA2G2A, COL1A1, C7, GPC3, LUM, CTHRC1, SERPINF1, RARRES2), hematopoietic stem cell (SPARCL1, ENPP2, EDN1, IGFBP7, CRIP2, A2M, SOCS3, ID1), Monocytes (S100A8, LYZ, S100A9, IL1B, S100A12, CXCL2, BCL2A1, CCL3, CCL20, CXCL3, G0S2, PLAUR, FCN1, SOD2, C15orf48, EREG, IL1RN), Decidual (IGFBP1, LUM, DKK1, IGFBP2, DCN, RBP1, IGFBP4, PRL, IGFBP5, HSD11B1, IGFBP6, CD248, TIMP3, CFD), Dendritic/Macrophage 1 (APOE, APOC1, CCL18, CD74, SPP1, C1QC, FTL, RNASE1, CXCL3, CTSZ), Cytotrophoblasts (PAGE4, CGA, TINAGL1, SPINT1, SPINT2, LDHB).
