Abstract

This unit describes a protocol for the differentiation of human embryonic stem cells (hESCs). To generate spin embryoid bodies (EBs), known numbers of hESCs are deposited into low-attachment, round-bottomed 96-well plates in a serum-free medium supplemented with growth factors. The cells are then aggregated by centrifugation, initiating formation of EBs of uniform size. The spin EBs generated using this technique differentiate efficiently and synchronously along the lineages preferentially induced by the combinations of growth factors to which the cells are exposed. The 96-well format permits an assessment of the effects of different combinations of growth factors in the same experiment, fac..
