Sunjay Kaushal, MD, PhD, surgeon in the Division of Cardiovascular Thoracic Surgery at Children's Memorial Hospital and assistant professor of surgery at Northwestern University Feinberg School of Medicine, who headed the study, believes these results show great promise for the growing number of children with congenital heart problems. With this potential therapy option these children may avoid the need for a heart transplant.
"Due to the advances in surgical and medical therapies, many children born with cardiomyopathy or other congenital heart defects are living longer but may eventually succumb to heart failure," said Kaushal. "This project has generated important pre-clinical laboratory data showing that we may be able to use the patient's own heart stem cells to rebuild their hearts, allowing these children to potentially live longer and have more productive lives."
Cells were obtained from patients ranging in age from a few days after birth to 13 years who were undergoing routine congenital cardiac surgery. Findings show that the number of heart stem cells was greatest in neonates and then rapidly decreased with age, and that the highest numbers of these stem cells are located in the upper right chamber of the heart, or the right atrium. The study also showed that the cardiac stem cells are functional and have the potential for use in repairing the damaged heart. Up until now, heart stem cell studies have addressed the adult diseased heart, but this is the first and largest systematic study to focus on children.
"Heart disease in children is different than heart disease in adults," said Kaushal. "Whereas adults might suffer heart failure from coronary artery disease or atherosclerosis, heart failure in children primarily occurs because they acquire cardiomyopathy or have a congenital condition in which the heart chambers are small or in the wrong position causing the heart to pump inefficiently. The potential of cardiac stem cell therapy for children is truly exciting," said Kaushal. Pending FDA approval, Kaushal hopes to begin clinical trials with children in the fall.
The study was funded by grants from the National Institutes of Health, the Thoracic Surgical Foundation for Research and Education, the Children's Heart Foundation and the North Suburban Medical Research Junior Board.

Diversity in the brain – How millions of neurons become unique
26.09.2018 | Universität Basel
Our brain is a complex network with innumerable connections between cells. Neuronal cells have long thin extensions, so-called axons, which are branched to increase the number of interactions. Researchers at the Max Planck Institute of Biochemistry (MPIB) have collaborated with researchers from Portugal and France to study cellular branching processes. They demonstrated a novel mechanism that induces branching of microtubules, an intracellular support system. The newly discovered dynamics of microtubules has a key role in neuronal development. The results were recently published in the journal Nature Cell Biology.
From the twigs of trees to railroad switches – our environment teems with rigid branched objects. These objects are so omnipresent in our lives, we barely...
The Fraunhofer FEP has been involved in developing processes and equipment for cleaning, sterilization, and surface modification for decades. The CleanHand Network for development of systems and technologies to clean surfaces, materials, and objects was established in May 2018 to bundle the expertise of many partnering organizations. As a partner in the CleanHand Network, Fraunhofer FEP will present the Network and current research topics of the Institute in the field of hygiene and cleaning at the parts2clean trade fair, October 23-25, 2018 in Stuttgart, at the booth of the Fraunhofer Cleaning Technology Alliance (Hall 5, Booth C31).
Test reports and studies on the cleanliness of European motorway rest areas, hotel beds, and outdoor pools increasingly appear in the press, especially during...
The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.
This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.
Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
