Precise, robust and scalable directed differentiation of pluripotent stem cells is an important goal with respect to disease modeling or future therapies. Using the AggreWell™400 system we have standardized the differentiation of human embryonic and induced pluripotent stem cells to a neuronal fate using defined conditions. This allows reproducibility in replicate experiments and facilitates the direct comparison of cell lines. Since the starting point for EB formation is a single cell suspension, this protocol is suitable for standard and novel methods of pluripotent stem cell culture. Moreover, an intermediate population of neural precursor cells, which are routinely >95% NCAM(pos) and Tra-1-60(neg) by FACS analysis, may be expanded and frozen prior to differentiation allowing a convenient starting point for downstream experiments.
