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 [...]
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.
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.
While the overall economy may be flagging, Maryland says that its biotech industry is booming. And the governor wants to keep the momentum going with a few new industry incentives. Gov. Martin O’Malley told reporters that the biotech industry added more than a thousand jobs in the last three months; that’s 10 percent of the [...]
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 [...]
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 [...]
The scramble to come up with a faster and cheaper way to sequence a genome just got a credible new contender which aims to do the job for the bargain basement rate of $30. The first time scientists sequenced a human genome, the price tag hit $3 billion. That price point has quickly plunged to [...]
What three trends are most important to pharma these days? Generics, emerging markets and personalized medicine, according to the Harvard Business Review. Branded generics are the wave of Big Pharma’s future, HBR says. These branded versions of off-patent meds sell at higher prices than regular generics do, but are cheaper than the branded meds themselves. They give [...]
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.
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 [...]
