Promotion of wound repair in old mice by local injection of macrophages

Abstract

Application of peritoneal macrophages to experimentally induced cutaneous wounds of old mice accelerates healing to levels almost comparable to those of untreated young animals. Slightly greater acceleration is observed when macrophages are obtained from young as opposed to old donors. These findings are consistent with a defect in macrophage function as a cause of impaired wound healing in senescence and suggest a possible therapeutic strategy.
