The present invention addresses the problem of providing a method for acquiring and producing kidney progenitor cells having a high degree of purity from a cell population obtained by inducing differentiation of pluripotent stem cells into kidney progenitor cells by identifying a kidney progenitor-specific cell surface antigen marker. A method for preparing kidney progenitor cells obtained by inducing differentiation of pluripotent stem cells, which includes: (i) a step for cultivating pluripotent stem cells under conditions that induce differentiation into kidney progenitor cells； and (ii) a step for sorting a cell population from the cells obtained in step (i) by using at least one cell surface marker selected from the group consisting of CD9(-), CD55(-), CD106(+), CD140a(+), CD140b(+), CD165(+), CD271(+), and CD326(-).本發明之課題係在於提供藉由鑑定腎前驅細胞特異性細胞表面抗原標記，而自由多能性幹細胞分化誘導成腎前驅細胞之細胞群體中，取得並製造純度較高的腎前驅細胞之方法。一種製造由多能性幹細胞分化誘導而成之腎前驅細胞之方法，其係包含：(i)將多能性幹細胞在誘導向腎前驅細胞分化之條件下進行培養之步驟；以及(ii)自步驟(i)所獲得之細胞中，使用選自CD9(-)、CD55(-)、CD106(+)、CD140a(+)、CD140b(+)、CD165(+)、CD271(+)、及CD326(-)所組成群組之至少1種細胞表面標記來篩選細胞群體之步驟。
