Why the Zebrafish will Never Die of a Broken Heart
More than 6,700 people in Oxfordshire were affected by heart failure in 2011/12.
By looking at the way the zebrafish’s heart repairs itself after it is damaged the team hopes to find ways to treat people who have had heart attacks and those who develop heart failure.
She said: “Humans cannot regenerate hearts after they are damaged, but the zebrafish can. By learning how they do this could help us treat humans in the future.
“A zebrafish heart beats at 180bpm, two to three times faster than a human heart, so we cannot take a sharp picture from a live specimen.
“The colours in the picture show the green cells are heart muscle cells, and the red and blue staining shows components that make up the muscle.
“We can see that the cells are already really active. We can see what genetic steps they go through to regenerate.
“While it is clearly very useful with our research I also think it is a picture which could be hung on a wall.”
“It’s astonishing to discover the ‘Caught in the Net’ picture is actually a developing zebrafish heart. These creatures have the ability to heal their own hearts, something humans sadly can’t do.
“Studying their hearts in such fine detail will help us discover their secret so that one day we can repair damaged hearts, and help people with heart failure.”
