Specially Engineered Immune Cells Ward off AIDS

A group of scientists have demonstrated that specially engineered stem cells could be used to fights off AIDS, successfully testing the approach in mice engineered to develop immune systems similar to humans. The investigators started with the observation that a small group of people who are virtually immune to HIV have disabled CCR5 receptors on [...]

New Spin on DNA Delivery: Enhanced Delivery Method of DNA Payloads into Cells

Chang Lu and his chemical engineering research group at Virginia Tech have discovered how to “greatly enhance” the delivery of DNA payloads into cells. The description of their work will be featured on the cover of Lab on a Chip, the premier journal for researchers in microfluidics. Lu’s ultimate goal is to apply this technique [...]

Scientists Grow New Lungs Using ‘Skeletons’ of Old Ones

For someone with a severe, incurable lung disorder such as cystic fibrosis or chronic obstructive pulmonary disease, a lung transplant may be the only chance for survival. Unfortunately, it’s often not a very good chance. Matching donor lungs are rare, and many would-be recipients die waiting for the transplants that could save their lives.

Antiviral Stem Cell Squad Dispatched to Fight Deadly HIV

Building on research work undertaken in Germany, City of Hope investigators near LA have used modified stem cells loaded with gene sequences to fight off HIV. And the scientists in the study say that the work points to a possible cure for the dread virus, which has killed millions of people around the world.

Importance of Human Genome Sequencing Still Debated – 10 Years Later

Craig Venter has never been reluctant to credit himself for a lead role in sequencing the human genome. And he’s certainly not the least bit shy about placing a high value on the overall significance of the work. “I think it’s far more important than walking on the Moon; not much has happened since walking [...]

Stem Cells Used to Create Abnormal Heart Cells

Researchers at Mount Sinai School of Medicine have for the first time differentiated human stem cells to become heart cells with cardiomyopathy, a condition in which the heart muscle cells are abnormal. The discovery will allow scientists to learn how those heart cells become diseased and from there, they can begin developing drug therapies to [...]

Stem Cell Culturing Breakthrough

For the first time, human embryonic stem cells have been cultured under chemically controlled conditions without the use of animal substances, which is essential for future clinical uses. The method has been developed by researchers at Karolinska Institutet and is presented in the journal Nature Biotechnology.

Muscle Stem Cell Movements Documented

When muscle tissue experiences trauma or disease, such as muscular dystrophy, stem cells in the muscle known as “satellite cells” respond to repair and regenerate the muscle. These cells are particularly important in neuromuscular diseases, such as muscular dystrophy, which affect muscle stability and repair. Now, University of Missouri researchers have used time-lapse photography [...]

GE Healthcare invests $5M in CardioDx

GE Healthcare has entered an alliance with CardioDx to co-develop diagnostic technologies to improve the care and management of patients with cardiovascular disease. Building on the alliance, the GE Healthymagination Fund, a new equity fund that makes investments in highly promising healthcare technology companies, has invested $5 million in CardioDx as part of a Series [...]

Stem Cells: In Search of a Master Controller

With thousands of scientists across the globe searching for ways to use adult stem cells to fight disease, there’s a growing emphasis on finding the “master regulators” that guide the differentiation of stem cells. New research from Rice University and the University of Cambridge suggests that a closely connected trio of regulatory proteins fulfills [...]
