In guinea pigs, a single human gene Tbx18 has transformed ordinary heart cells into rare 'pacemaker' cells. These pacemaker cells regulate cardiac rhythm. The research is a step toward the goal of a biological fix for irregular heartbeat, which at present is tackled by drugs or electronic pacemakers, its investigators said.

Gene Turns Heart Cells into Pacemaker
In guinea pigs, a single human gene Tbx18 has transformed ordinary heart cells into rare 'pacemaker' cells. These pacemaker cells regulate cardiac rhythm. The research is a step toward the goal of a biological fix for irregular heartbeat, which at present is tackled by drugs or electronic pacemakers, its investigators said.
