Transplantation of a person’s adult stem cells into his/her own heart muscle improves the person’s ability to walk, lessens pain, and reduces death.
Researchers from the nation’s (US) largest stem cell study for heart disease affirm the value of using one’s own stem cells to treat heart disease. Aiming to prompt the growth of small blood vessels that make up the microcirculation of the heart muscle that is compromised in severe angina, Douglas W. Losordo, from Northwestern University Feinberg School of Medicine (Illinois, USA), and colleagues injected subjects' own purified stem cells (CD34+ cells) into their own hearts. As a result, the team improved subjects’ ability to walk, lessened pain, and reduced death. They conclude that: “Autologous CD34 cell therapy was associated with improved exercise tolerance and reduced angina in no-option patients with intractable angina.”
