doi: 10.1002/advs.202503480

Figure Lengend Snippet: Abnormal infiltration of monocyte‐derived CCR2 + macrophages in OAPS decidua and their pro‐inflammatory roles. A) Bar plot showing the proportions of MDMs in decidual immune cells from OAPS patients and HCs in scRNA‐seq data. B) FCM analysis of the proportion of CCR2 + macrophages in the decidua from OAPS patients (n = 11) compared with HCs (n = 18). C) Representative images for CCR2 + and CCR2 − macrophages from the decidua of OAPS patients and HCs under the transmission electron microscope. Scale bar: 2 µm. D) Bubble plot showing the functional gene expressions in different types of decidual myeloid cells based on scRNA‐seq data. E) Bar plot showing the GO terms of marker genes in decidual MDMs. F) Bar plot showing the KEGG terms of marker genes in decidual MDMs. G) GSEA indicates the term of inflammatory response is significantly enriched in decidual CCR2 + macrophages. H) Bar plot showing the relative expression levels of genes related to inflammatory factors in decidual CCR2 + and CCR2 − macrophages, as detected using RT‐qPCR (n = 3). I) Representative immunoblots and semi‐quantified results of Arginase 1, NF‐κB P65, and STAT3 expressions in decidual CCR2 + and CCR2 − macrophages from OAPS patients (n = 3). J) Representative immunofluorescence images for CD14 (green), CCR2 (red), IGFBP1 (croci), HLA‐G (cyan), and DAPI (blue) co‐staining in decidua from HCs. Scale bar: 1000 µm. K) Representative immunofluorescence images for CD14 (green), CCR2 (red), IGFBP1 (croci), HLA‐G (cyan), and DAPI (blue) co‐staining in decidua from OAPS patients. Scale bar: 2000 µm. L) Line chart showing the effects of medium supernatants from CCR2 + and CCR2 − macrophages on HTR‐8/SVneo proliferation, as measured by CCK‐8 (n = 3). M) Bar plot showing relative expression levels of CASP3 , MMP2 , and MMP9 genes in HTR‐8/SVneo treated with supernatants from CCR2 + and CCR2 − macrophages, as detected by RT‐qPCR (n = 3). Data in (A) and (B) are presented as mean ± SD and analyzed using Student's t ‐test. Data in (H) and (I) are presented as mean ± SD and analyzed using a paired t ‐test. Data in (L) and (M) are presented as mean ± SD and analyzed using one‐way ANOVA with Dunnett's multiple comparisons test. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001.
