Leukemia, stem cell scientists, N.Y. mayor get Lasker Awards

Sir John Gurdon

One of the most prestigious prizes in medicine is being awarded this year to scientists working on stem cells and leukemia — and to New York‘s mayor for his fight to cut tobacco use (…)

The Lasker Basic Medical Research Award goes to John Gurdon, 76, of Cambridge University and Shinya Yamanaka, 47, of Kyoto University and San Francisco‘s Gladstone Institute of Cardiovascular Disease. Their work has helped pave the way for the possibility of made-to-order stem cell treatments for individual patients

Gurdon began working with frog eggs in the 1950s and was the first to successfully clone

ITALY – Do vegetable stem cells aid in hair growth? IAP investigates into misleading advertisement.

“Younger and more hair with vegetable stem cells” is the pitch which increasingly being read in the advertisements in the major Italian newspapers. But is it true? Are we faced with a new frontier for medicine, capable of obtaining benefits for humans from vegetable stem cells similar to embryonic and adult stem cells? Among experts in the sector, including pharmacologists, cosmologists, and dermatologists, skepticism is common: “It’s a slogan,” said Silvio Garattini, the director of the Mario Negri Institute of Pharmacological Research, “which is not based on any scientific evidence.” “I

Piloting stem cells presents a challenge for treatments

Complications and unanticipated side-effects that have slowed the progression of stem cell studies from the lab to the clinic could soon change, researchers say.
For a decade, stem cells have tantalized scientists and patients with their promise to regenerate damaged tissues and offer treatments for incurable diseases.

No one hears, however, about the individuals who died due to complications of surgery, said Dr. Hans Keirstead, a Canadian researcher who made a paralyzed rat walk back in 2004 by injecting its spinal cord with cells derived from human embryonic stem cells.
Keirstead’s lab at the University of California-Irvine just received approval

Meat produced without animals using stem cells

If we are to produce sustainable and healthy food for the global population of nine billion people that is projected in 2050, then we must think along completely new lines.

Imagine this: With a clear conscience you sink your teeth into a juicy and tasty hamburger. No animal has been slaughtered to deliver the meat, no new forest felled to make way for animal feed, no bovine methane burps have affected the climate and no slurry has been released into the environment. The hamburger also has a satisfyingly low fat content and the fat consists only of fatty acids that

Stem cell breakthrough: Monitoring the on switch that turns stem cells into muscle

Image via Wikipedia

In a genetic engineering breakthrough that could help everyone from bed-ridden patients to elite athletes, a team of American researchers—including 2007 Nobel Prize winner Mario R. Capecchi—have created a “switch” that allows mutations or light signals to be turned on in muscle stem cells to monitor muscle regeneration in a living mammal. For humans, this work could lead to a genetic switch, or drug, that allows people to grow new muscle cells to replace those that are damaged, worn out, or not working for other reasons (e.g., muscular dystrophy). In addition, this same discovery also gives researchers
