Scientists use gold nanoparticles to improve stem cell transplants for heart disease patients.
A team of bioengineers from Tel Aviv University is currently developing a scaffold to help regenerate heart muscle through the use of autologous stem cells. The scientists, led by Dr. Tal Dvir, aim to replace damaged cardiac tissue in heart attack patients by creating a scaffold out of collagen and gold nanoparticles, and then infusing it with the patient’s own stem cells to stimulate the rejuvenation of cardiomyocytes.

Mesenchymal Stem Cells are more effective than bone marrow mononuclear cells in treating Ischemic Cardiomyopathy
A year long clinical trial by the University of Miami Miller School of Medicine has demonstrated that autologous [the patient’s own] mesenchymal stem cells (the type of stem cells found in teeth) are a safe and effective stem cell source for regenerative therapies for the treatment of Ischemic Cardiomyopathy. The study also determined that mesenchymal stem cell treatment was more effective than treatments utilizing bone marrow mononuclear cells. Continue reading →
Hypoxic-Ischemic brain injury can be caused by a number of ailments including cardiac arrest (heart attack), respiratory arrest, incomplete suffocation and more. The incidence in the United States of hypoxic-ischemic brain injuries is 1-8 in every 1000 births. Researchers at Nagoya University have used stem cells from human exfoliated deciduous teeth (SHED) to treat neonatal mice with hypoxic-ischemic brain injuries. They have found that this treatment leads to neurological and pathophysiological recovery of these injuries. These finding indicate that SHED may be utilized in the future for a novel neuroprotective therapy for hypoxic-ischemic brain injuries. Continue reading →
At this year’s American Heart Association Scientific Sessions, abstracts reporting on clinical trials involving the use of stem cells to treat various types of heart disease, such as Acute Myocardial Infarction and Ischemic Cardiomyopathy, were presented.
