Pulmonary Valve for Children Engineered from Stem Cells.

An organic pulmonary valve replacement for children has been engineered with stem cells to grow as the child does to prevent multiple surgeries.

Researchers at the University Of Maryland School Of Medicine have created a pulmonary valve replacement for pediatric patients suffering from congenital heart conditions.  The scientists, led by Dr. David L. Simpson, differentiated the patient’s own [autologous] stem cells into heart valvular cells and then arranged these cells to bioengineer a pulmonary valve that was unique to each patient.  The valve was created in vitro [outside the body] so the next step would be to develop protocols to undertake clinical trials.   Continue reading
