A biodegradable tissue to repair hearts after a heart attacks or to cure congenital malformations. A tissue that acts like a porous, accordion-like medium onto which cardiac stem cells are ‘implanted’ has been created by scientists from the prestigious Massachusetts Institute of Technology in Boston (MIT). This “bioscaffolding” integrates perfectly with cardiac tissue and creates a biological “band-aid” that is slowly reabsorbed and repairs cardiac muscle.
Compared to similar previous attempts, explained George Engelmayr in “Nature Materials” magazine, the advantage of the “bioscaffolding” is that it faithfully mirrors cardiac tissue structurally and mechanically, and
No Waiting for the Stem Cell Research Debate To Finish
While the debate on stem cell research rages on, Donald Cecil couldn’t afford to wait for research. Donald badly needed treatment for his heart which was damaged by a series of heart attacks. Luckily, he found a stem cell treatment, Vescell in Thailand by using […]
Muscle wasting linked to old age might one day be treated using stem cells, claim US scientists.
A University of Colorado team transplanted cells into mice and saw the muscle more than double in size – staying that way even into old age.
They say their work, reported in Science Translational Medicine, may have promise in treating muscle-wasting conditions such as muscular dystrophy.
A UK expert said producing a human treatment might be difficult.
Stem cells are cells found in the body which can divide and become a variety of different types of tissue.
Scientists believe they could potentially help treat a large number

Scientists at the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa have discovered a powerful new way to stimulate muscle regeneration, paving the way for new treatments for debilitating conditions such as muscular dystrophy.
The research, to be published in the June 5 issue of Cell Stem Cell, shows for the first time that a protein called Wnt7a increases the number of stem cells in muscle tissue, leading to accelerated growth and repair of skeletal muscle.
“This discovery shows us that by targeting stem cells to boost their numbers, we can improve the body’s ability to repair

In a genetic engineering breakthrough that could help everyone from bed-ridden patients to elite athletes, a team of American researchers—including 2007 Nobel Prize winner Mario R. Capecchi—have created a “switch” that allows mutations or light signals to be turned on in muscle stem cells to monitor muscle regeneration in a living mammal. For humans, this work could lead to a genetic switch, or drug, that allows people to grow new muscle cells to replace those that are damaged, worn out, or not working for other reasons (e.g., muscular dystrophy). In addition, this same discovery also gives researchers
