Scientists map the genomic blueprint of the heart

Scientists at the Gladstone Institutes have revealed the precise order and timing of hundreds of genetic "switches" required to construct a fully functional heart from embryonic heart cells—providing new clues into the ...

Finished heart switches stem cells off

It is not unusual for babies to be born with congenital heart defects. This is because the development of the heart in the embryo is a process which is not only extremely complex, but also error-prone. Scientists from the ...

Scientists make strides toward fixing infant hearts

Researchers at Rice University and Texas Children's Hospital have turned stem cells from amniotic fluid into cells that form blood vessels. Their success offers hope that such stem cells may be used to grow tissue patches ...

Biologists use flies, mice to study Down syndrome

A novel study involving fruit flies and mice has allowed biologists to identify two critical genes responsible for congenital heart defects in individuals with Down syndrome, a major cause of infant mortality and death in ...
