AP: Cardiac cells could repair heart after attack

Scientists say they've found cells in the hearts of mice that can make new muscle after a heart attack, raising hopes that doctors can one day help the human heart repair itself. Steve Houser, director of the Cardiovascular Research Center at Temple, said the new research underscores what other teams have reported on potential repair cells in the heart, including some cells being tested in humans. While he says the study will "stir the field" of heart regeneration studies, he cautioned that "very little in the cardiac world has translated from mice to man."
