Compositions, methods of making compositions, and methods of using compositions for treatment of liver diseases, disorders, and damage are provided. The compositions can include chemically induced liver progenitor cells (CLiPs), and/or cell-free materials formed from the CLiPs such as extracellular vesicles (EVs) such as exosomes. In some embodiments, the compositions and/or methods are effective to reduce existing hepatic collagen or the formation of new hepatic collagen; and/or reduce the amount of existing fibrosis or the formation of new fibrosis in a subject in need thereof.

The present invention pertains to hepatocytes, liver progenitor cells, cholangiocytes, liver sinusoidal endothelial progenitor cells, liver sinusoidal endothelial cells, hepatic stellate progenitor cells, hepatic stellate cells, and liver cellular tissue models, as well as to methods for preparing these cells. The present invention also pertains to a cell fraction comprising liver progenitor cells, liver sinusoidal endothelial progenitor cells, or hepatic stellate progenitor cells. The present invention also pertains to a pharmaceutical composition or kit comprising the above-mentioned cells, a liver cellular tissue model, or a cell fraction. The present invention also pertains to: a method for screening liver disease treatment agents; a method for evaluating the hepatotoxicity of drugs, hepatocytes for infectious disease models, and a method for preparing the same; infectious disease model tissues and a method for preparing the same; as well as a method for screening infectious liver disease treatment agents.

In related-art methods of differentiating pluripotent stem cells into a desired cell type, there has not been established a differentiation induction method using human ES/iPS cells and being stable and highly efficient. The use of complicated culture steps is a large problem. In addition, there are also large problems in, for example, that the speed of cell differentiation is low, and hence long-period culture is required, and that the differentiation efficiency is low, and hence it is difficult to obtain a sufficient number of required cells. A method of inducing differentiation into a desired cell type, which induces differentiation within a short period of time and with high efficiency by the use of a Sendai virus vector capable of expressing a transcription factor, and as required, the use of a pluripotent stem cell in which an expression amount of a POU5F1 protein has been substantially removed or reduced, is provided.

Methods, compositions and kits for producing functional neurons, astroctyes, oligodendrocytes and progenitor cells thereof are provided. These methods, compositions and kits find use in producing neurons, astrocytes, oligodendrocytes, and progenitor cells thereof for transplantation, for experimental evaluation, as a source of lineage- and cell-specific products, and the like, for example for use in treating human disorders of the CNS. Also provided are methods, compositions and kits for screening candidate agents for activity in converting cells into neuronal cells, astrocytes, oligodendrocytes, and progenitor cells thereof.
