  • Patent number: 11712451
    Abstract: 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.

  • Patent number: 11518982
    Abstract: A method for producing a mesenchymal cell line derived from a vertebrate adipose tissue, and a mesenchymal cell line derived from a vertebrate adipose tissue produced by the method. Advantageously, a method for producing a mesenchymal cell line derived from a vertebrate adipose tissue is achieved more simply, in a shorter period of time, and more efficiently. Also, a mesenchymal cell line is derived from a vertebrate adipose tissue produced by the production method. The method for producing a mesenchymal cell line derived from a vertebrate adipose tissue comprises: (A) inducing differentiation of one or more cells selected from a stromal vascular fraction comprising a mesenchymal stem cell, an adipose progenitor cell, and a stromal cell of a vertebrate adipose tissue into a mature adipocyte; and (B) inducing dedifferentiation of the mature adipocyte obtained in step (A) to obtain a mesenchymal cell line derived from the vertebrate adipose tissue.
