Italians in new research breakthrough

(refiling to clarify cells are stem cells).
    (ANSA) - Rome, November 12 - Researchers at Genoa university have identified a rare stem-cell population present in the peripheral blood of healthy mice that actively participates in tissue repair according to a paper published in the online journal Scientific Reports. The stem cells, discovered by Claudia Lo Sicco and Roberta Tasso of the department of experimental medicine at Genoa university, were injected into mice with tail fractures and subsequently migrated and engrafted in wounded tissues, ultimately differentiating into tissue-specific cells. "Until now there has been no evidence for the presence of cells with a healing capacity circulating in healthy conditions," the abstract said.
    "These findings uncover the existence of constitutively circulating cells that may represent novel, accessible, and versatile effectors of therapeutic tissue regeneration," it concluded.
