| abstract |
Provided are genes that can be used as markers for whether certain cells, particularly undifferentiated cells including tissue stem cells, are pluripotent or undifferentiated. In the present invention, a Stm containing Stm1 gene, a gene that is specifically expressed in an undifferentiated state if it has pluripotency, was discovered and the present invention was completed. Accordingly, the present invention is a kit for determining a differentiation state of a cell, wherein (a) a factor that specifically reacts with a Stm gene or a Stm gene product; and (b) whether the Stm gene is expressed in the cell. A kit comprising: means for confirming. |
