This unit describes the published Matrigel mattress method. Briefly, we describe the preparation of the mattress, replating of the human induced pluripotent stem cell–derived cardiomyocytes (hiPSC‐CM) on the Matrigel mattress, and hiPSC‐CM mattress maintenance. Adherence to this protocol will yield individual, robustly shortening hiPSC‐CMs, which can be used for downstream applications. © 2017 by John Wiley & Sons, Inc.

Basic Protocol 1:

  • One 35‐mm dish containing day 30 hiPSC‐CMs (unit 4.2; Ohnuki, Takahashi, & Yamanaka, ; frozen hiPSC‐CMs should be thawed and cultured for 3 to 5 days before dissociation)
  • D‐PBS without CaCl 2 or MgCl 2 (Life Technologies, cat. no. 14190144)
  • TrypLE Express (Life Technologies, 12604013)
  • hiPSC‐CM medium (see recipe)
  • Matrigel Growth Factor Reduced Basement Membrane Matrix (Corning, cat. no. 356230)
  • 15‐ml conical centrifuge tube (e.g., Corning Falcon)
  • Small cell scraper (Corning, cat. no. 3010)
  • 2‐μl Gilson repeat pipettor with tips
  • Timer
  • Delta TPG dish (Delta TPG DISH (50/pack), 0.17 mm black; Fisher Scientific, cat. no. 12‐071‐34) for experiments (typically three dishes per group)
  • Light microscope
  • Additional reagents and equipment for counting cells using a hemacytometer (e.g., unit 1.13; Behar et al., )
