Human stem cell treatment gets mice with MS-like condition walking again

By - May 28, 2014 1 Picture
When scientists at the University of Utah injected human stem cells into mice disabled by a condition similar to multiple sclerosis, they expected the cells to be rejected by the animals' bodies. It turned out that the cells were indeed rejected, but not before they got the mice walking again. The unexpected finding could have major implications for human MS sufferers. Read More

"Heart disease-on-a-chip" could usher in an age of personalized medicine

By - May 23, 2014 1 Picture
When we've previously heard about "organs on a chip," they've been miniature recreations of healthy organs. If they're being used for research into the treatment of health problems, however, then it only makes sense that those "organs" should have something wrong with them. With that in mind, a group of Harvard scientists have created the world's first lab-grown sample of functioning human heart tissue that has a cardiovascular disease. Read More

In what could mark a significant breakthrough in the treatment of heart disease, researchers at the University of Washington (UW) have successfully repaired damaged tissue in monkey hearts using cells created from human embryonic stem cells. The findings demonstrate an ability to produce these cells on an unprecedented scale and hold great potential for restoring functionally of damaged human hearts. Read More

First transfusions of "manufactured" blood planned for 2016

By - April 22, 2014 1 Picture
According to the World Health Organization, approximately 107 million blood donations are collected globally every year. Nonetheless, blood is often in short supply – particularly in developing nations. Despite new safeguards, there's also still the risk of incompatibility, or of infections being transmitted from donors to recipients. Charitable organization the Wellcome Trust hopes to address these problems, by developing the ability to manufacture blood outside of the body. Last week, it announced that test subjects should begin receiving transfusions of blood made with lab-grown red blood cells by late 2016. Read More

Rats receive lab-grown esophagi

By - April 16, 2014 1 Picture
Ordinarily, when patients require a total or partial replacement of their esophagus, tissue from their own stomach or intestine is used. This doesn't always result in a fully-functioning organ, plus it also involves the surgical removal of the needed material. Now, however, scientists have come a step closer to being able to grow a new esophagus from the patient's own stem cells, and in fact have already done so – with rats. Read More

Scientists give stem cells a performance boost ... by putting them on steroids

By - April 14, 2014 1 Picture
Stem cells are highly promising for the treatment of everything from HIV to leukemia to baldness. In many cases, however, a great number of them must be used in order have a noticeable effect, which makes treatments impractical or expensive. Now, scientists at Harvard-affiliated Brigham and Women's Hospital have found that a smaller number of stem cells can still get the job done, if they're first hopped up on steroids. Read More

Finger-prick technique opens door for DIY stem cell donors

By - March 24, 2014 3 Pictures
Harvesting samples for producing stem cells can be rather painful. Techniques can involve collecting large amounts of blood, bone marrow or skin scrapes. The reality is intrusive measures such as these can be very off-putting. But what if it was as simple as a finger-prick? Such a DIY approach, which is so easy it can be done at home or in the field without medical staff, has been developed by researchers at Singapore's A*STAR Institute of Molecular and Cell Biology (IMCB).
