• How Stem Cells are Changing the Way we Think About Disease

    Treating disease is about fixing broken parts — about replacing cells that no longer work as they should, repairing tissues that falter and boosting systems that fail. But curing disease is a different matter. To cure disease, you have to do all of that and more. You have to remove the pathological cause of the problem and to ensure that it doesn’t return. This requires teasing out where rogue cells went wrong and finding a way to nurture healthier ones to replace them.

  • Stem Cells Show Promise for Repairing Damaged Hearts

    The promise of stem cell research just got a lot brighter.

    Recently, there was some very good news from the world of medicine. For the first time, stem cells were injected into the hearts of humans who had suffered serious heart damage, and patients improved dramatically. It appears that, as everyone hoped, the stem cells grew into new heart cells to replaced the damaged tissue. This is the promise of all stem cell research: to repair or replace damaged organs that otherwise would never recover. In principle, we can someday use the same technique to replace damaged livers, kidneys, spinal cords, cartilage, and virtually all other tissues in the human body.

  • The Future of Stem Cells

    Stem cells have moved from biological obscurity to the forefront of political and technological debate in the U.S. and around the world. Investigators are confident that someday stem cells will be the foundation for fantastic cures and therapies. Yet critics argue that stem cell research raises ethical questions no less profound than the pursuit of the nuclear bomb more than 60 years ago.

    The complexity of the science and the rapid proliferation of business, ethical and political issues pose a challenge for anyone wishing to stay well informed on this vital subject.
