Bioengineers from the University of California, Berkeley, have utilized adult stem cells to create a network of pulsating heart cells encased in a silicon chip, effectively modeling cardiac tissue. To capture the dynamic structure and function of the heart, the scientists loaded the stem cells into a layered, 3-D scaffold to mimic the geometry of the organ and included channels on either side of the chip to act as blood vessels, thus replicating the organ’s natural exposure to nutrients and therapies.

Researchers from Okayama University have developed a method to treat the congenital heart defect known as hypoplastic left heart syndrome [HLHS] by utilizing a specialized cardiac stem cell. In a Phase I clinical trial conducted on children suffering from HLHS, the scientists concluded that, because the young stem cells in children are more abundant and self-renewing than those in adults, intracoronary injection of stem cells is a safe and feasible approach to treating the condition.

According to new research from the National Yang-Ming University, mesenchymal stem cells [MSCs] hold the ability to limit atherosclerotic plaque formation, thereby preventing the onset of harmful endothelial lesions. The research team, led by Shih-Chieh Hung, transplanted MSCs into animal models with atherosclerosis and observed significant reduction in plaque formation. They also saw an increase in blood vessel dilation, which prevents further plaque development, indicating good endothelial health.
Researchers led by Eduardo Marbón of the Cedars-Sinai Heart Institute have developed a method to prolong the lives of patients with Duchenne Muscular Dystrophy [DMD] through the infusion of cardiac stem cells. The stem cells reverse the loss of cardiac muscle caused by the genetic disease, preventing heart failure that would otherwise limit a patient’s life expectancy to age 25.
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.
As reported on the front page of the New York Times Science section, clinical applications of stem cell based therapies are accelerating at a rate that will revolutionize the medical field in a matter of years. In the United States alone, there are currently over 4000 therapies in clinical trials for the treatment of heart disease, blindness, spinal cord injuries, diabetes, H.I.V., and other diseases, injuries, and traumas.

A team of scientists from the Wyss Institute, Boston Children’s Hospital, and Harvard’s Medical School, Stem Cell Institute, and School of Engineering has created a model to study and develop treatments for the genetic heart disorder Barth Syndrome by utilizing a patient’s own stem cells in conjunction with an organ-on-a-chip. The chip was outfitted with proteins to mimic the cellular environment of the heart, causing the patient’s stem cells to differentiate into diseased heart tissue. The tissue was then studied to not only determine the cause of the disease, but to treat the diseased tissue as well.
Research teams from Cedars-Sinai Heart Institute and the Minneapolis Heart Institute with funding from CIRM [California Institute for Regenerative Medicine] are moving to Phase 2 Clinical Trials for a treatment that utilizes cardiac stem cells to repair severe heart damage. The treatment development was led by Eduardo Marbán, a director at the Cedars-Sinai Heart Institute and founder of Capricor. This groundbreaking treatment involves the injection of stem cells into the coronary artery, which then migrate to the heart and promote the regrowth of healthy heart muscle.

Researchers from the University of Vermont have developed a novel and effective application of mesenchymal stem cells [the same type found in Dental Stem Cells] to treat heart disease. The MSCs, when transplanted along with cardiac stem cells into the heart [in an animal model], produced a “cocktail” of protective ligands that improved the grafting success of the cardiac stem cells.
Utilizing autologous [the patient’s own]stem cells to regenerate heart muscle, scientists at the Novant Health Group have successfully treated patients that suffered from severe heart attacks; potentially limiting the long term loss of tissue and preserving heart function for victims. The patient’s own mesenchymal stem cells [the same type as dental stem cells] are harvested and then implanted back into the damaged area, where they recruit surrounding cells to aid in the repair process.
