Root Or Shoot: Power Struggle Between Genetic Master Switches Decides Stem Cell Fate, Growth Orientation in Plants

The first order of business for any fledgling plant embryo is to determine which end grows the shoot and which end puts down roots. Now, researchers at the Salk Institute expose the turf wars between two groups of antagonistic genetic master switches that set up a plant’s polar axis with a root on one end and a shoot on the other.

UCSD researcher pens ‘Stem Cells for Dummies’

Lawrence Goldstein, Ph.D., will speak at the Book Works on March 2. Courtesy UCSD Early last year, a literary agent phoned Lawrence Goldstein, Ph.D., and asked if he wanted to write a book. But not just any book. The agent wanted him to write “Stem Cells for Dummies.” Director of the UCSD Stem Cell Program, Goldstein is a professor of cellular and molecular medicine, a Howard Hughes Medical …

Home Current Issues Science & Medicine Is Stem Cell Research Ethical?

Today, a man lies dying of liver failure in a hospital. There is little expectation that he will be one of the lucky few to receive a transplant before he becomes too ill to save. Even if he did receive a transplant, he will be burdened with taking …

Congress moves as stem cell limits lifted

WASHINGTON (Reuters) – President Barack Obama signed an order lifting eight years of restrictions on federal funding of human embryonic stem cell research on Monday as scientists gushed, activists cheered and shares in stem cell companies rose …

This letter is in reference to the letter from Amy Hofer in the Feb. 9 Argus Leader. In the letter Hofer attacked our fine state senator, Ben Nesselhuf, in a mean-spirited way. She called him names and made accusations that would get her sent to the …

Stempeutics to launch its stem cell based new drug in India by 2012

Stempeutics Research, a biotechnology company developing stem cell based medicinal products, is all set to introduce its investigational new drug (IND) in India by 2012. The drug is being developed in India is for acute myocardial infarction and critical limb ischemia.

Notch-blocking drugs kill brain cancer stem cells, yet multiple …

Working with mice, Johns Hopkins scientists who tested drugs intended to halt growth of brain cancer stem cells – a small population of cells within tumors that perpetuate cancer growth – conclude that blocking these cells may be somewhat effective …

Stem Cell Therapy Removes Cell Receptor That Attracts HIV

UCLA AIDS Institute researchers successfully removed CCR5 a cell receptor to which HIV-1 binds for infection but which the human body does not need from human cells. Individuals who naturally lack the CCR5 receptor have been found to be essentially resistant to HIV…

Study: Stem cell research money provides jobs, taxes

The Maryland Stem Cell Research Commission is using a new report to bolster its appeal for at least level funding in next year’s budget.
