(A) TSNE plot generated from unsupervised clustering analysis of single cell RNA-seq data from kidney biopsies of lupus patients generated by the Accelerating Medicines Partnership (AMP) project (right panel). Feature plot showing GPNMB expression, revealing 3 myeloid cell clusters with GPNMB expression (CM1, CM4, and CM2) (left panel). (B) Bar plot showing percentage of GPNMB expressing cells in kidney-infiltrating cell clusters and dot pot showing relative GPNMB expression levels.
