description To provide methods for producing iPS cells using epithelial cells such as keratinocytes.SOLUTION: Disclosed methods comprise; an initiation step of introducing a reprogramming gene or translation product thereof into epithelial cells to conduct nuclear initiation; a step of adhered cell culture comprising culturing the cells subjected to the initiation step on a culture surface coated with laminin or a fragment thereof under xeno-free conditions; and prior to the initiation step, a step of culturing epithelial cells under xeno-free conditions for use in the step of initiation, where the reprogramming gene includes Oct3/4 gene, Klf4 gene and Sox2 gene, the laminin and laminin fragments have an integrin binding site, the cells to which the reprogramming gene or translation products thereof has been introduced in the initiation step are cultured in a medium containing a ROCK inhibitor, and the culture step comprises culturing a tissue including the outer root sheath of a fallen hair with a culture medium of high calcium concentration and then with a culture medium of low calcium concentration to proliferate epithelial cells.SELECTED DRAWING: Figure 1 【課題】ケラチノサイト等の上皮系細胞を用いてiPS細胞を製造する、製造方法を提供する。【解決手段】核の初期化を行うリプログラム遺伝子又はその翻訳産物を、上皮系細胞に導入することを含む初期化工程と、初期化工程を経た細胞を、ゼノフリー条件で、ラミニン又はその断片でコートされた培養面上で付着培養する付着培養工程と、初期化工程前に、初期化工程で使用する上皮系細胞をゼノフリー条件で培養する培養工程と、を備え、リプログラム遺伝子が、Oct3/4遺伝子、Klf4遺伝子及びSox2遺伝子を含み、ラミニン及びラミニン断片は、インテグリン結合部位を有し、初期化工程においてリプログラム遺伝子又はその翻訳産物を導入した後の細胞を、ROCK阻害剤を含む培地で培養することを含み、培養工程は、抜毛により取得された外毛根鞘を含む組織を、高カルシウム培地で培養後、低カルシウム培地で培養し、上皮系細胞を増殖させる工程を含む。【選択図】図1
