Rats receive lab-grown esophagi

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

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

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).

Stem cell-based treatment for baldness a step closer

As one of the follically-challenged, any new breakthroughs in the area of hair regeneration will generally get my attention. When stem cells first started to gain widespread media attention I, no doubt like many others, thought a full head of hair was just around the corner. But despite numerous developments, years later my dome is still of the chrome variety. Providing the latest cause for cautious optimism, researchers have now developed a way to generate a large number number of hair-follicle-generating stem cells from adult cells. Read More
