Fat Cell Suppressor Emerges from the Stromal Shadows

Where fat cells originate, exactly, has been less than clear. Yes, fat cells have their precursors, such as adipogenic stem cells, but these tend to hide in the stromal vascular fraction, a shadowy region where cells of different types are hard to distinguish. To shine a bright light on stromal cells, scientists based at Ecole Polytechnique Fédérale de Lausanne (EPFL) and Eidgenössische Technische Hochschule Zürich (ETHZ) resorted to a technique called single-cell transcr
