1. Set-up for dish coating, media preparation, and hPSC maintenance

1. Dish coating
   1. Vitronectin (VTN) coating
      1. Place vials of VTN in a 37 °C water bath until fully thawed, then mix thoroughly.
      2. For a 100 mm Petri dish, mix 7 mL of 1x phosphate buffered saline (PBS) with 0.5 mg/mL VTN, add VTN solution to the dish, and incubate at room temperature (RT) for 1 h.
   2. Basement membrane matrix coating​
      1. Thaw vials of basement membrane matrix (see Table of Materials) on ice at 4 °C overnight.
      2. For one....

Figure 1: NC induction. (A) Timeline and treatments for NC induction from day 0 to day 10. (B) The morphology and formation of NC ridges were monitored every 2 days by bright field microscopy. Cells at each time point after day 2 were co-stained for AP2A (red) and SOX10 (green). All immunofluorescence pictures were counterstained with DAPI. Red arrows indicate the structures of ridges. (C) qRT-PCR analysis for the expression profile of NC markers from day 2&#....
