A ground-breaking study that may change how heart attacks are treated.

When a person has a heart attack a piece of muscle in a person’s heart dies from lack of blood flow , it scars over and is lost.  But a team of researchers from the Cedars-Sinai Heart Institute in Los Angeles has proven that those muscles may not necessarily be gone forever.

An image released by Karolinska University Hospital shows part of the operation.

The world’s first transplant of a fully synthetic organ has been carried out by surgeons – a windpipe created using the patient’s stem cells and an artificial “scaffold”.  A month ago a 36-year-old cancer patient received the organ at the Karolinska University Hospital in Stockholm.

Scientists Develop Pill to Mend Broken Heart

Taking the pill when a heart attack occurs, the muscles and blood vessels around the organ could rebuild themselves.

Researchers in Britain claim they may be just a decade away from perfecting a way to persuade the heart to rejuvenate – a process thought to be impossible just five years ago.  They have developed a pill that triggers the heart to repair itself after an attack and is a major step towards one of the “holy grails” of medical research.

Chemical Discovered Which ‘Makes Bone Marrow Repair Skin’

Skin grafts trigger repair by bone marrow cells.

The chemical which summons stem cells from bone marrow to the site of a wound has been discovered by scientists in the UK and Japan.

The study, published in Proceedings of the National Academy of Sciences, identified the distress signal – HMGB1.

The authors believe it can be used to put “a megaphone in the system” to improve the treatment of injuries such as burns and leg ulcers…
