The present invention provides a gene marker useful for detecting and / or identifying cells at each stage in the process of differentiating bone marrow cells into osteoblasts via mesenchymal stem cells. A bone marrow cell, a cell after culturing a bone marrow cell, and a mesenchymal stem cell by detecting the expression level or expression level difference of at least one of genes having a specific base sequence Only prior to selective culture, cells, mesenchymal stem cells, osteoprogenitor cells, or osteoblasts are detected and / or separated. [Selection figure] None |
