Abstract

Many human embryonic stem (hES) and induced pluripotent stem (hiPS) cell differentiation protocols begin with the formation of three-dimensional aggregates of cells called embryoid bodies (EBs). Traditional EB formation methods result in a heterogeneous population of EB sizes and shapes, which then undergo heterogeneous differentiation efficiencies. AggreWellTM400 and AggreWellTM800 use the spin-EB method to force the aggregation of a defined number of cells, thereby controlling EB size and generating a population of uniform EBs. Moreover, the dense array of microwells on the bottom surface of AggreWellTM400 provide for the rapid and simple production of thousands of EBs at a time.
