Bone marrow cell transplants to benefit those with heart disease
Date:2/24/2010

Tampa, Fla. (February 24, 2010) Two studies published in the latest issue of Cell Transplantation (18:12) may lead to new treatments for the treatment of heart diseases. The first study, carried out by a team of Brazilian researchers, found that cell transplantation of bone marrow mononuclear cells (BMMCs) directly into the heart benefited patients suffering from refractory angina. A separate study carried out by researchers in the Peoples' Republic of China found that apelin, a newly described inotropic peptide, improves heart function following transplantation of BMMCs.

ReACT bone marrow cell transplants help refractory angina

A team of Brazilian researchers has evaluated the safety and efficacy of a surgical procedure involving multiple injections into the heart (intramyocardial) of a bone marrow mononuclear cells (BMMCs) formulation derived from the patient (autologous) called "Refractory Angina Cell Therapy (ReACT)". The researchers found that the procedure benefitted all eight of the refractory angina patients in the study, all of whom had previously received surgical revascularization.

"The large fraction of monocytes in the ReACT formula appears to be related to the new blood vessel growth, or angiogenesis, that restores perfusion on the myocardial ischemic areas after the cell transplantation," said corresponding author Dr. Nelson Americo Hossne, Jr. of the Paulista School of Medicine, Federal University of Sao Paulo. "For our patients, angina symptom relief began as early as three months post-procedure with continuing improvement through the twelfth month and sustained improvement past 18 months. Symptom relief improved in all patients, suggesting that the effect is sustained, not transitory."
