Figure Lengend Snippet: A ) Immunofluorescence microscopic images of histological sections through snap-frozen human endocervix tissue (top) and side view images of a human Endocervix Chip (bottom) showing the mucus layer visualized with Jacalin (red) and Wheat Germ Agglutinin (WGA, green) (bar, 25 μm, tissue; 1 mm, chip). B ) Venn diagram showing the number of unique and common proteins detected in a native pregnancy mucus plug versus mucus cleaved from Endocervix Chips (N=2 human donors) using proteomic analysis. C ) Bar graph showing differential abundance of undecorated, sialylated, sialofucosylated (SF), and sulfated O-glycans in mucus cleaved from Endocervix Chips versus Ectocervix Chips determined using nano LC-MS glycomic profiling. Structures are grouped based on glycan composition and retention time (Hex_HexNAc_NeuAc_Fuc| RT) (N=3-4 chips per condition; Mean ± SD, one-way ANOVA; E2= estradiol, PH= progesterone and estradiol, * p <0.05, ** p <0.01, *** p <0.001).
Article Snippet: The chips were then perfused with the mucin-binding lectins 4μg/ml Jacalin (Fluorescein; Vector Laboratories, FL-1151-5) and 5μg/ml Wheat Germ Agglutinin (CF568 red fluor, 76221-784) in Hank’s Balanced Salt Solution, HBSS++ for 2 hours at 30μl/hour and subsequently perfused with HBSS++ for additional 2 hours prior to imaging.
