Using cryoinjury – damaging the heart through contact with extreme cold in order to mimic cellular damage caused by myocardial infarction – investigators found that neonatal mouse hearts can fully recover normal function following a mild injury, though neglect to regenerate after a severe injury. Published on the web by the journal Developmental Biology, the analysis shows that cardiac regeneration strategies should be based on the type and severity of heart injury. ‘Using models such as for example zebrafish and neonatal mice that regenerate their hearts naturally, we can begin to identify essential molecules that enhance center repair,’ said Ellen Lien, PhD, of The Saban Analysis Institute of Children's Hospital LA.By determining the way the body reacts to dietary and environmental stimuli and manages microbial and viral interactions, we try to improve wellbeing and healthier ageing.
