Scientists restore blood cells destroyed in simulated heart attack research
SCIENTISTS have managed to restore brain cells destroyed by a lack of blood to the brain, as can happen with a cardiac arrest. The US researchers, writing in eNeuro, induced very low blood pressure in rats – as happens when the heart stops – which led to a loss of 95 per cent of the neurons in the hippocampus region of the brain. They were then injected with a molecule that encourages cells called astrocytes to help the neurons recover. Two months later the rats' neurons had recovered to 50 per cent of normal levels.
