摘要： [Problems to be solved] An objective of the present invention is to provide methods for regenerating or repairing damaged tissues using adrenomedullin. Another objective is to provide pharmaceutical agents that comprise adrenomedullin as an active ingredient for regenerating or repairing damaged tissues.
[Means for Solving the Problems] To solve the above problems, the present inventors administered adrenomedullin (hereinafter indicated as AM) or physiological saline to C57BL/6 mice, and counted the numbers of mononuclear cells and Sca-1-positive cells in the blood. The result showed that AM increased the numbers of mononuclear cells and stem cell antigen-1-positive cells in the blood. It was also shown that by administering AM to a mouse model of pulmonary emphysema and a rat model of acute myocardial infarction, the quantity of bone marrow-derived cells that migrated and settled into the damaged tissues increased, and the recruited bone marrow cells differentiated into blood vessels, alveoli, and cardiac muscle at the lesion sites. Further, decrease in infarct size, suppression of the enlargement of alveolar diameter, and improvement of organ functions were confirmed in the models of myocardial infarction and pulmonary emphysema.
