TestYour donations are helping us fund a £260,000 research project looking at how genetic mistakes stop the heart developing correctly early in our lives.

Studying the early development of the heart is a vital part of the science behind our Mending Broken Hearts Appeal. We were all able to grow a new, whole heart once - in the womb, before we were born. But later in life, we can't regrow or repair our hearts if they are damaged by a heart attack.

Professor Deborah Henderson at the University of Newcastle and her team are researching one of the genetic mistakes that can cause congenital heart disease. Approximately 1 in 145 babies are born with faulty hearts, leading to many of them needing operations throughout their lives.

Most of these heart defects are caused by genetic errors, but many of the specific genes that are responsible have yet to be identified.

Donations from our supporters are helping us give £260,000 to fund Professor Henderson’s study, which will look at a gene called Vangl2, which is thought to play an important role right at the start of life, in the developing embryo.

The team will study the gene’s effects, in mice, on a blood vessel called the outflow tract. As the embryo grows, this blood vessel eventually turns into all the main arteries in the body. Their findings will improve our understanding of the causes of heart defects, and could give clues about how they may be treated or prevented.

In the coming years, scientists like Professor Henderson will study how human hearts grow and develop at the beginning of our lives. If we can find out how to turn this lost ability back on, we could develop a new cure for heart failure - the ultimate aim of Mending Broken Hearts.
