PROCÉDÉ DE PRÉPARATION DE CELLULES SOUCHES DE TISSU PULMONAIRE HUMAIN ET PROCÉDÉ D'INDUCTION DE LA DIFFÉRENCIATION EN CELLULES ÉPITHÉLIALES ALVÉOLAIRES HUMAINES
[Abstract] Provided are: a method of preparing cells that simultaneously express a type II alveolar epithelial cell marker and a stem cell marker, including a process of isolating and extracting constituent cells from human lung tissue, and a process of separating and culturing lung tissue stem cells from the obtained isolated cells； human lung tissue stem cells that are obtained from the above method of preparation and are able to differentiate into alveolar epithelial cells； a method of inducing differentiation into human lung epithelial cells, consisting of culturing the above human lung tissue stem cells； human alveolar epithelial cells prepared through the above method of inducing differentiation； and a method of screening that uses the above human lung tissue stem cells or human alveolar epithelial cells.
