First Biological Pacemaker using Human Stem Cells developed

A group of scientists from the McEwen Centre for Regenerative Medicine developed the first functional pacemaker cells from human stem cells.
●    The invention will help in paving the way for alternate, biological pacemaker therapy.
●    The study was published in December 2016 the journal Nature Biotechnology.
●    The scientists used a developmental-biology approach to ascertain a specific protocol for generating the pacemaker cells.
●    The study stated that sinoatrial node cardiomyocytes derived from human pluripotent cells function as a biological pacemaker.
●    It goes on to explain that human pluripotent stem cells can be manoeuvred in 21 days to develop into pacemaker cells, which regulate heart beats with electrical impulses.
●    The human pacemaker cells were tested in rat hearts. 
●    Pluripotent stem cells hold the potential to differentiate into more than 200 different cell types that make up every tissue and organ in the body.
●    Sinoatrial node pacemaker cells are the heart's chief pacemaker. It controls the heartbeat throughout life.
