    摘要: This invention provides a method for stably producing airway epithelial cells from pluripotent stem cells. Specifically, the invention relates to a method for producing airway epithelial cells from pluripotent stem cells comprising steps: (1) culturing pluripotent stem cells in a medium containing activin A and a GSK3β inhibitor; (2) culturing the cells obtained in Step (1) in a medium containing a BMP inhibitor and a TGFβ inhibitor; (3) culturing the cells obtained in Step (2) in a medium containing BMP4, retinoic acid, and a GSK3β inhibitor; (5) subjecting the cells obtained after Step (3) to three-dimensional culture in a medium containing a GSK3β inhibitor, FGF10, and a ROCK inhibitor; and (6) subjecting the proximal airway epithelial progenitor cells obtained in Step (5) to three-dimensional culture in a medium containing a ROCK inhibitor.

    摘要: The present invention relates to an isolated polypeptide comprising an amino acid sequence having at least 70% identity to the amino acid sequence of SEQ ID NO:2 or to the amino acid sequence of SEQ ID NO:25; or encoding a polypeptide comprising the amino acid sequence of SEQ ID NO: 2 or the amino acid sequence of SEQ ID NO: 25, wherein the polypeptide is capable of phosphorylating myosin light chain. The present invention also relates to an isolated nucleic acid encoding said polypeptide; a composition and a kit comprising the polypeptide or the nucleic acid; a vector comprising the isolated nucleic acid; an isolated host cell comprising the nucleic acid or the vector; an antibody that specifically binds to the polypeptide of the present invention; and a transgenic non-human animal which expresses the nucleic acid of the present invention. The invention further relates to a method of detecting the presence of a nucleic acid of the present invention; and a method of producing a neukinase polypeptide of the present invention.
