Mesenchymal stem cells (MSCs) in skeletal muscle have been known to be important for muscle repair in response to non-physiological injury, predominantly in response to chemical injections that significantly damage muscle tissue and induce inflammation. University of Illinois researchers, ...]]> http://www.medindia.net/news/exercise-triggers-adult-stem-cells-to-enhance-muscle-health-97246-1.htm http://www.medindia.net/news/researchers-formulate-mode-of-directing-stem-cells-to-boost-bone-formation-and-bone-strength-97231-1.htm UC Davis Health System scientists led research team has built a novel technique to enhance bone growth by using a molecule. When it is injected into the bloodstream, it directs the body's stem cells to travel to the surface of bones. Once these cells are guided to the bone surface by this molecule, the stem cells differentiate into bone-forming cells and synthesize proteins to enhance bone growth. The study, which was published online today in INature Medicine/I, used a mouse model of osteoporosis ...]]> http://www.medindia.net/news/researchers-formulate-mode-of-directing-stem-cells-to-boost-bone-formation-and-bone-strength-97231-1.htm http://www.medindia.net/news/acid-attack-survivor-katie-pipers-eyesight-restored-after-stem-cell-surgery-97133-1.htm Using stem cells surgeons in Britain have restored the sight of model and television presenter Katie Piper, 29, who was partially blinded after an acid attack on her face arranged by her former boyfriend Daniel Lynch, 35.Katie suffered third degree burns and had a damaged left eye and was scarred for life in the 2008 acid attack. She endured hundreds of operations, skin grafts and wore a mask up to 23-hours a day to stretch the scar tissue around her eyes as part of her recovery.Surgeons at the ...]]> http://www.medindia.net/news/acid-attack-survivor-katie-pipers-eyesight-restored-after-stem-cell-surgery-97133-1.htm http://www.medindia.net/news/stem-cells-may-act-as-catalyst-for-hepatitis-research-97058-1.htm Hepatitis C is a mysterious disease as it has different effects on different people. It can also cause inflammation and organ failure. But no one is sure why some people are very susceptible to the infection, while others are resistant. Scientists believe that if they could study liver cells from different people in the lab, they could determine how genetic differences produce these varying responses. However, liver cells are difficult to obtain and notoriously difficult to grow in a lab ...]]> http://www.medindia.net/news/stem-cells-may-act-as-catalyst-for-hepatitis-research-97058-1.htm http://www.medindia.net/news/environment-conducive-to-growth-of-blood-forming-stem-cells-identified-96799-1.htm The environment in which blood-forming stem cells survive and thrive within the body has been identified by scientists with the new Children's Research Institute at UT Southwestern Medical Center. This is an important step toward increasing the safety and effectiveness of bone-marrow transplantation. Institute investigators led by Dr. Sean Morrison asked which cells are responsible for the microenvironment that nurtures haematopoietic stem cells, which produce billions of new blood cells every day....]]> http://www.medindia.net/news/environment-conducive-to-growth-of-blood-forming-stem-cells-identified-96799-1.htm http://www.medindia.net/news/stem-cell-therapy-useful-in-secondary-progressive-multiple-sclerosis-96664-1.htm bStem cell therapy may be beneficial in people with secondary progressive multiple sclerosis, according to a recent study/b. Multiple sclerosis is a condition that leaves the affected person with severe disability, ultimately requiring managed care. bIn multiple sclerosis, the covering of the nerves called myelin sheath is damaged; this is followed by damage of the underlying nerves/b.
