Nuclear reprogramming substances are contacted with a somatic cell and, after culture, cell population is fractionated based on the expression of Sca-1 or EpCam and CD34. By sorting Sca-1-negative CD34-negative cells or EpCam-positive CD34-negative cells, a cell population having high possibility of iPS cell formation can be selected. On the other hand, Sca-1-positive CD34-positive cells or EpCam-negative CD34-positive cells are useful as a source of myocardial cell or a progenitor cell thereof having a low risk of tumor formation. |
