Robust Differentiation of Human iPSCs into a Pure Population of Adipocytes to Study Adipocyte-Associated Disorders

Overview

This protocol describes the generation of a pure adipocyte population from induced pluripotent stem cells (iPSCs) through differentiation into mesenchymal stem cells (MSCs) using retinoic acid. A Nile red staining sorting approach is employed to isolate pure adipocytes.

Key Study Components

Area of Science
