The study by Kohda et al. (1) in this issue of Diabetes is a remarkable contribution to the field of adipose tissue biology and metabolic research. The authors have used cutting-edge single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics to dissect the intricate cellular interactions within adipose tissue during obesity-induced fibrosis. Their identification of novel cell-to-cell communications between macrophages and fibroblasts, particularly the role of Mincle-expressing macrophages and the oncostatin M (Osm) axis, offers a fresh perspective on the pathogenesis of adipose tissue fibrosis (1). The detailed analysis of subclusters of macrophages and fibroblasts and their dynamic interactions provides a comprehensive understanding of the cellular crosstalk driving fibrosis. This work not only enhances our knowledge of adipose tissue remodeling but also opens new avenues for therapeutic interventions targeting obesity-related metabolic disorders.
