Summary

Automatic Translation

Humane induserte pluripotente stamcelleavledede kardiomyocytter (hiPSC-CMs) tilbyr et alternativ til å bruke dyr til preklinisk kardiotoksisitetsscreening. En begrensning for den utbredte adopsjonen av hiPSC-CMs i preklinisk toksisitetsscreening er den umodne, fosterlignende fenotypen til cellene. Her presenteres protokoller for robust og rask modning av hiPSC-CM.
