摘要： An object of the present invention is to provide, for example, a more practical wound healing accelerator that more effectively accelerates wound healing. More specifically, a feature of the present invention is to provide, for example, a more practical wound healing accelerator that is easily obtained in a larger amount than that of peripheral blood platelet and has a better wound healing effect than that of peripheral blood platelet. The present invention employs a platelet-like cell population coexpressing one or more platelet surface markers and one or more mesenchymal cell surface markers. A wound healing accelerator containing the platelet-like cell population is a more practical wound healing accelerator that more effectively accelerates wound healing. The platelet-like cell population is easily obtained in a larger amount than that of peripheral blood platelet and has a better wound healing effect than that of peripheral blood platelet.
