PHILADELPHIA - Mammalian heart tissue may be capable of regenerating itself after serious injury, according to a new study by researchers at The Wistar Institute. Experiments with a strain of laboratory mice known as MRL mice detailed their potent ability to renew damaged heart tissue with minimal scarring. A report on the findings will appear in the online edition of the Proceedings of the National Academy of Sciences on August 7. Importantly, regeneration of heart tissue in the mice was achieved without the use of drugs, transferred cells or tissues, such as stem cells, or any other intervention. The observed healing is a native capacity of this particular strain of mice.
