The single cell revolution has been going on for a few years, but adipocytes have lagged, because their large size and fragility make them unamenable to traditional whole cell approaches. Our (long and expensive!) optimization of single nucleus strategies for adipose tissue finally pays off. Read our paper (A single cell atlas of human and mouse white adipose tissue. Nature, 2022) in Nature to learn about the diversity of cell types in mouse and human adipose tissue, the discovery of several unique adipocyte subpopulations, and associations between these cells and metabolic diseases like T2D. Cells are featured across visceral and subcutaneous depots, as well as in leanness and obesity. This work was spearheaded by Margo Emont.
