SCIENTISTS have created "miracle mice" that can regenerate amputated limbs or damaged vital organs, making them able to recover from injuries that would kill or permanently disable normal animals. The experimental animals are unique among mammals in their ability to regrow their heart, toes, joints and tail. http://www.theaustralian.news.com.au/common/story_page/0,5744,16417002%5E30417,00.html And, notably "When we injected fetal liver cells taken from those animals into ordinary mice, they too gained the power of regeneration. We found this persisted even six months after the injection."
