Proteome analysis of CD169+ macrophages in lymph nodes with breast tumor metastases using Nanostring GeoMX (Figure 3A) were compared to gene expression of the CD169+ (SIGLEC1) clusters in a public data set of Human breasts tumor single cell RNA Seq data from the Michigan Portal for the Analysis of NGS Data (MiPanda) (29) (Figure 3B). This evidence concerns the gene SIGLEC1 and breast neoplasm.
