Stem cells from surgery leftovers could repair damaged hearts

Scientists have for the first time succeeded in extracting vital stem cells from sections of vein removed for heart bypass surgery. Researchers funded by the British Heart Foundation (BHF) found that these stem cells can stimulate new blood vessels to grow, which could potentially help repair damaged heart muscle after a heart attack.

The research, by Paolo Madeddu, Professor of Experimental Cardiovascluar Medicine and his team in the Bristol Heart Institute (BHI) at the University of Bristol, is published in the leading journal Circulation.

Cardiac stem cell patient introduced

Doctors with the University of Louisville and officials with Jewish Hospital Friday introduced the recipient of one of the world’s first adult cardiac stem cell infusion to treat congestive heart failure.

Michael Jones, 66, had his own cardiac stem cells injected directly into heart scar tissue, using a cardiac catheterization procedure, according to a news release.

Dr. Mark Slaughter, chief of the Division of Cardiothoracic Surgery at the University of Louisville and director of the Heart Transplant and Mechanical Assist Device Program at Jewish Hospital, performed coronary artery bypass surgery on Jones on March 23, according to the release.

‘Leftover’ veins from heart surgery yield stem cells

A University of Bristol team extracted stem cells from the veins, then used them to stimulate new blood vessel growth in mice, Circulation reports.

The researchers say their findings could bring treatments to repair damaged heart muscle one step closer.

However, a stem cell expert warned that they remained some years away.

Stem cells are attractive to medical researchers because they have the ability to produce many different types of human cell, opening up the possibility of repair or renewal for tissues ravaged by disease or injury (…)
