Abstract: Disclosed is an efficient and non-genetically modified iPSC-induced, industrialized single clone selection platform, and a use. The platform can efficiently perform reprogramming, and only requires the use of a minimal number of reprogramming factors (OCT4, SOX2, E6, E7). During the single clone separation stage of the present invention, SSEA4/TRA-1-60 is used as a screening marker, and a large number of single cell clones are obtained by means of flow cytometry. The platform described in the present invention has advantages such as high reprogramming efficiency, high safety, easy operation, and large-scale production.

Abstract: Provided are a method for differentiating human induced pluripotent stem cells into oligodendrocytes, and a kit and the use. The method comprises culturing stem cells by means of using at least one of the following culture media: a neural induction complete culture medium, an N2 culture medium, a B27 culture medium and an OPC maturation culture medium. More preferably, the induction of oligodendrocytes by an OPC maturation culture medium with puerarin increases the number of oligodendrocytes by 30% compared with a culture medium without puerarin.

Abstract: Provided in the present disclosure are a KHL polypeptide, and the use thereof in the preparation of a TABP-EIC cell. In addition, also provided in the present disclosure are a KHL polypeptide conjugate, a tumor-antigen-binding polypeptide containing the KHL polypeptide, a DNA molecule, a carrier, a host cell and a pharmaceutical composition. The tumor-antigen-binding polypeptide is composed of the KHL polypeptide, a transmembrane domain and/or a signal transduction domain.
