Stem-like progenitor cell that exclusively forms heart muscle Future therapies for failing hearts are likely to include stem-like cells and associated growth factors that regenerate heart muscle. Scientists have just taken an important step towards that future by identifying a stem-like “progenitor” cell that produces only heart muscle cells.
Scientists restore normal function in heart muscle cells of diabetic rats Working with heart muscle cells from diabetic rats, scientists have located what they say is the epicenter of mischief wreaked by too much blood sugar and used a sugar-gobbling enzyme to restore normal function in the glucose-damaged cells of animal heart muscles.
3-D heart printed using multiple imaging techniques Congenital heart experts have successfully integrated two common imaging techniques to produce a three-dimensional anatomic model of a patient's heart. This is the first time the integration of computed tomography and three-dimensional transesophageal echocardiography has been used in this way. A proof-of-concept study also opens the way for these techniques to be used in combination with a third tool -- magnetic resonance imaging
]Key protein may affect risk of stroke Studies on mice reveal that a special protein in the brain's tiniest blood vessels may affect the risk of stroke. Scientists are learning how the blood-brain barrier develops and what makes the capillaries in the brain different from small blood vessels in other organs.
