New research has identified a possible way to manipulate certain stem cells to generate new bone tissue. The results of this investigation could vastly improve the outcome for people with skeletal injuries or conditions such as osteoporosis. Stem cells are undifferentiated cells that have the potential to specialize and undertake any function. Image: A new study looks at how to encourage stem cells to form new bone tissue rather than...

Study overturns dogma of cancer metabolism theory
Scientists at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have discovered that squamous cell skin cancers do not require increased glucose to power their development and growth, contrary to a long-held belief about cancer metabolism. Image shows squamous cell skin cancer tumors with lactate production (a byproduct of glucose...

Scientists design protein that prods cancer-fighting T-cells
The new immunotherapy drug is designed to fight cancer while avoiding common side effects. This illustration depicts how the new protein, in red, binds only to the beta and gamma receptors, and not to cells with a third kind of receptor.

Modulating copper levels in the treatment of heart disease
An article published in Experimental Biology and Medicine provides new insights regarding the use of trientine (TETA), a copper chelator traditionally used to treat copper overload conditions such as Wilson’s disease, in the treatment of heart disease. The study, led by Dr. Y. James Kang, professor from the Regenerative Medicine Research Center at Sichuan University...

Blood pressure may explain higher dementia risk in blacks
Older black adults with high blood pressure, and especially black men, show more severe cognitive declines than white adults who have high blood pressure, according to new research. The University of Michigan-led study published Wednesday in the American Heart Association’s journal Hypertension, suggests blood pressure may help explain why black adults—who are more likely to...

Drug may delay MS disability for some
The medication is called rituximab (Rituxan). It’s used to treat a number of conditions, including certain blood cell cancers and the autoimmune condition rheumatoid arthritis. The new Swiss study found that MS patients taking the drug reported less disabling symptoms over a 10-year period than those who didn’t. People taking rituximab also had a slower...
