Generating and Characterizing Adipose Spheroids from Adipose-Derived Stromal/Stem Cells.

Abstract

Advances in technology and automation over the past several decades have made it feasible to perform high-throughput compound screening with cell spheroids, a valuable approach for drug discovery. It is entirely feasible to generate multiple 384-well plates containing adipose spheroids from cryopreserved, single-donor, adipose stem cells, thus incorporating genetic diversity into the discovery stages of research. In this protocol, we describe our method for isolating primary humanadipose stem cells and synthesizing cell spheroids comprised of mature adipocytes and stromal cells. Also included are representative outcome measurements useful for characterizing adipocyte metabolism and health. Wherever possible, we describe technologies that can be used to automate characterization and increase throughput.
