With gene therapy there's no need to miss a beat.
Researchers at Cedars-Sinai Heart Institute in Los Angeles created biological pacemaker cells by inserting a single gene, called Tbx18, into a virus and injecting the engineered virus into the hearts of guinea pigs bred to have arrhythmia.
The gene prompts the creation of an exact replica of a raisin-sized node in the heartís upper right chamber which normally maintains regular heart rhythms. Tbx18 transformed heart muscle cells, called cardiomyocytes, into a colony of natural pacemaker cells.
How soon until heart repair becomes routine? I'm thinking some time in the 2020s or maybe the 2030s at the latest.
