According to cardiologists hundreds and thousands of
babies born every year with defective hearts, heart valve abnormalities are one of the most common kinds of inherited heart defects In these babies.
Stem cells collected at birth from the umbilical cord from this babies may help doctors to provide new heart valves for them.
The researchers reported the findings today at the annual meeting of the American Heart Association.
The led reasearcher cardiac surgeon Dr.Ralf Sodian, says, surgeons can transplant new valves from human or animal donors, or from artificial material, these valves won’t grow as children do, they will need surgery several times in their lifetime, so the ultimate goal is to have a construct which is able to grow with the child and only have to do the surgery once,
Sodian, and his team created eight bio-engineered valves, which are acting much like natural heart valves as they were tested to handle blood flow and pressure.
Sodian hopes to begin experimenting with young lambs next year. He is eager to watch how this heart valves grow and function into the hearts of young lambs.

Stem Cell Test Treatment for Heart Attack PatientsJune 22nd, 2007 British scientists are to try out a new way to repair damage caused by heart attacks. By injecting patients' damaged hearts with stem cells from their own bone marrow scientists hope to regenerate tissue.
Children's Cord Blood is a Form of Biological InsuranceFebruary 5th, 2007 Frances Verter's first child, Shai, died before reaching her fifth birthday after a lifelong fight with cancer. When her second and third children were born, Verter decided to collect and store the blood from their umbilical cords, an option increasingly being presented to expecting parents around the nation.
Can British researchers bring an end to heart transplant?December 3rd, 2008 London researchers are on their way to find a technique what can be called a groundbreaking success in heart disease and research. The research is likely to put an end to the use of heart transplant.
Patient's own stem cell used for heart failureNovember 18th, 2008 In the first research of its kind, researchers in the University of Utah are trying to use body's own stem cell to treat heart failure. After drawing about 3 tablespoons of patients' own bone marrow, researchers will grow cardiac-repair cells -- believed to help heart muscles and improve blood flow -- in culture for about 12 days.
Stem Cell Trial For Heart Patients in UKMay 2nd, 2006 Timothy O’Brien, director of the Regenerative Medicine Institute (Remedi) in NUI Galway (Ireland) , is preparing tests involving 10 patients suffering from chronic heart conditions. They will have stem cells grafted on to their hearts, to see if this helps to repair the damage organs, avoiding the need for replacement.
Stem Cell Fish Research Shows New Ways to Treat Damage human Hearts November 9th, 2006 New information about how the hearts of tiny zebrafish regenerate could help in developing new ways to treat heart damage in humans, say Duke University Medical Center scientists. It's believed that the ability to regenerate damaged heart tissue is present in all vertebrate species but, for unknown reasons, humans and other mammals have "turned off" this regeneration function, according to background information in the article.
Chemical 'Band-aid' Prevents Heart Failure In Mice With Muscular DystrophyJuly 18th, 2005 A common chemical used in the manufacturing and pharmaceutical industries can repair damage to cardiac muscle cell membranes and prevent heart failure in mice with the genetic mutation that causes Duchenne muscular dystrophy, according to scientists at the University of Michigan Medical School. The mutation in the dystrophin gene causes the progressive deterioration of skeletal muscles seen in people with MD.
Newborn Babies Saves Life With Umbilical Cord Blood DonationMay 8th, 2006 Most hospitals discard cord blood after baby's birth, despite the fact that this precious cord blood contains stem cells that can be used in transplants for as many as 80 serious medical problems. Those include the most prevalent types of leukemia, metabolic disorders like Tay-Sachs disease, blood-related conditions such as sickle cell anemia and severe anemia problems.
