| abstract |
The present invention provides a method for converting mononuclear cells into multi-functional P stem cells (Multipotent stem cells). P stem cells are further converted into target cells. For example, when such P stem cells are injected into a damaged tissue site using chondrocytes, nerve cells, bone cells, or the like, the P stem cells are converted into tissue cells. A repairing action can be obtained, and a target cell can be directly injected into a damaged tissue cell site to obtain a repairing action. [Selection figure] None |
