Summary
Automatically generated
This protocol describes how to produce functional sinus nodal tissue from murine pluripotent stem cells (PSC). T-Box3 (TBX3) overexpression plus cardiac Myosin-heavy-chain (Myh6) promoter antibiotic selection leads to highly pure pacemaker cell aggregates. These “Induced-sinoatrial-bodies” (“iSABs”) contain over 80% pacemaker cells, show highly increased beating rates and are able to pace myocardium ex vivo.
