Are you aware that more than 250,000 persons in U.S. get an artificial pacemaker each year but this news would certainly bring smile on the faces of people suffering from heart ailments. A custom designed protein and gene delivery system has been successfully used by UC Davis researchers for restoring the normal heart rhythms in pigs with electronic pacemakers. This certainly gives a hint that scientists are very close to realizing bioengineering which could help in the treatment of more than 2.2 million Americans who are suffering from irregular heartbeats. As per Ronald Li, Leader of research team and associate professor, UC Davis School of Medicine Our study offers positive and direct evidence in living models that bioengineered cells can replace the electronic pacemaker. Our hope is to one day replace electronic pacemakers in people It is expected that this research would offer a permanent and more reliable alternative to implanted electronic devices.
