Zoomed-in images show SCS and medullary sinuses containing cancer cells and MGP expression on PROX1 + LECs (arrows). Blue, cytokeratin; red, MGP; green, PROX1. Scale bars, 125 μm. Images are representative of four individuals with similar results. Circles in the bar plots represent biological replicates (mean ± SEM, two-tailed, unpaired Student’s t -test). Metastatic LN, n = 4 patients; non-metastatic LN, n = 4 patients. Source data are provided as a Source Data file. e MGP expression in LECs of non-metastatic and metastatic LNs detected using Visium HD. f Gene Ontology (GO) enrichment analysis of the top DEGs (Wilcoxon rank-sum test, metastatic vs. distant LNs) using the EnrichR package. FDR-corrected p values are shown.

Article Snippet: Briefly, non-metastatic and metastatic LN sections were treated with anti-MGP antibody (1:100, Proteintech 10734-1-AP) or a negative control antibody (Rabbit IgG 1:100, Proteintech 30000-0-A) for 30 min.

Techniques: Expressing, Labeling, Immunostaining, Two Tailed Test

a MGP expression in LECs after CM treatment with anti-MGP antibody ( n = 5–6 HLECs), analyzed using one-way ANOVA linear mixed models (Sidak correction). b MGP expression in LECs exposed to anti-MGP antibody or recombinant MGP ( n = 6–10 HLECs), analyzed using two-way ANOVA linear mixed models (Sidak correction). c MGP expression in siRNA-silenced LECs ( n = 5 HLECs), analyzed by two-sided Mann–Whitney U -test. d Tube formation quantified by number of nodes, junctions and branches in MGP-silenced vs. control LECs, shown as geometric mean with 95% CI ( n = 17 HLECs), analyzed with a two-sided paired t -test. e Scratch assay of MGP-silenced and control LECs over 2 days (mean ± SEM; n = 13 HLECs), analyzed by repeated measures two-way ANOVA (matched full mixed model) with Sidak’s multiple comparisons. f Soluble MGP binding to cancer cells: MGP (His) was added with anti-His antibody (red), while the control (blue) contained only cancer cells with antibody. Histograms represent two independent experiments. g Ex vivo adhesion assay of T47D cells binding to lymphatic sinuses of six metastatic and five non-metastatic LNs from four and five patients, respectively (two-sided ratio paired t -test). LN sections were treated with anti-MGP or control antibody. The binding after control antibody was defined as 100% due to day-to-day variation. Example images show T47D cells binding after control vs. anti-MGP treatment to the same metastatic LN area. Adherent cells (some marked by yellow arrowheads) lie on top of tissue sections, focus adjusted to highlight cell adhesion. Scale bar: 50 μm. For box plots: center line = median; box = 25th–75th percentiles; whiskers = inner fences. Source data, non-significant p values and detailed experiment and n -numbers (biologically independent samples of cultured cells) are provided in the Source Data file.
