Abstract (original English)

The functional versatility of adipose tissue is mediated by various cell types and their capacity to transition between distinct functional states upon pathophysiological stimuli. Recent advances in single-cell transcriptomics have enabled the identification of novel and numerous cell types and states of adipocytes, adipose stem and progenitor cells, immune cells, vascular cells, and mesothelial cells. Significant efforts have been made to understand the key features and underlying processes of the cell subpopulations and to elucidate the cellular mechanisms of adipose tissue plasticity. In this review, we describe current knowledge of heterogeneous cell types and states in adipose tissue and emerging techniques to characterize them, offering fundamental knowledge for studying adipose tissue in the single-cell era.
