Transplanted human umbilical cord blood cells improved heart function in rat model of MI
Date:3/6/2014

heart's remodeling processes and to characterize alterations in the cardiac fiber architecture, the research team used diffusion tensor MRI (DTMRI), used previously to study myofiber structure in both humans and animals.

While most previous studies have been focused on the short term effects of UCBCs, their study on long term effects not only demonstrated evidence of significantly improved heart function in the treated rats, but also showed evidence of delay and prevention in terms of myocardial fiber structural remodeling, alterations that could have resulted in heart failure.

When compared to the age-matched but untreated rat hearts with MI, the regional myocardial function of nh-UCBC-treated hearts was significantly improved and the preserved myocardial fiber structure may have served as an "underlying mechanism for the observed function improvements."

"Our data demonstrate that nh-UCBC treatment preserves myocardial fiber structure that supports the improved LV regional and chamber function," concluded the researchers.

"This study provides evidence that UCBCs could be a potential therapy with long term benefits for MI" said Dr. Amit N. Patel, director of cardiovascular regenerative medicine at the University of Utah and section editor for Cell Transplantation. "Preservation of the myocardial fiber structure is an important step towards finding an effective therapy for MIs"
