Abstract

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% NCAMpos and Tra-1-60neg by FACS analysis, may be expanded and frozen prior to differentiation allowing a convenient starting point for downstream experiments.

Supplementary Figure 2Immunostaining of SCU-i10 NPCs differentiated for 11 days with antibodies to MAP2 (top row; red) and TuJ1 (second row; green). Merged images of both immunostains with Hoechst nuclear stain (third row; blue) are shown in the bottom row. Scale bars = 100 μm. Three differentiation media were compared - standard Neurobasal medium containing BDNF and GDNF (left column), mTeSR1 (center column) and NDM (right column). (PPT 3859 kb)

Supplementary Figure 3Characterization of the SCU-i10 human iPSC line. A) FACS analysis shows SCU-i10s are positive for SSEA-4, Tra-1-60 and Tra-1-81 and negative for SSEA-1; B) Karyotype is normal at p40 (performed by Cell Line Genetics, Madison, WI); C) Immunostaining of cells differentiated to endodermal lineage with antibodies to hepatocyte markers HNF4A (red) and albumin (green) with Hoechst nuclear stain (blue). Scale bar = 100 μm; D) Image captured from Supplementary Movie 1 which shows spontaneously beating area of differentiated cells. (PPT 1022 kb)
