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.

The invention relates to a method for inducing pluripotent stem cells, wherein a mammalian cell is contacted with a compound characterized by a general formula 1 wherein R.sup.1 is (CH.sub.2).sub.mE, with E being CCH or CN and m being 0, 1, or 2, and R.sup.2 is selected from F, CI, Br, OR.sup.3 and R.sup.3, with R.sup.3 being selected from H, (CH.sub.yF.sub.2-y).sub.n CH.sub.XF.sub.3-X, with n=0 or 1. The invention further relates to stem cells obtained by the method of the invention, and culture media comprising the compound of the invention.

The invention relates to a method of preparing pancreatic islet-like cell structures characterized by a unique combination of morphological and functional features which make them particularly suitable for use in both clinical and drug screening application, as well as to the pancreatic islet-like cell structures obtained therefrom.

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.

Provided is a method for producing myocardial cells from pluripotent stem cells. The myocardial cell production method provided by the present invention includes supplying an artificially produced synthetic peptide to a cell culture that contains pluripotent stem cells. The synthetic peptide is a peptide that contains a myocardial cell differentiation-inducing peptide sequence that induces pluripotent stem cells into myocardial cells. The myocardial cell differentiation-inducing peptide sequence is an amino acid sequence selected from the group consisting of (i) an amino acid sequence constituting the signal peptide of any protein belonging to the amyloid precursor protein (APP) family, (ii) a partial amino acid sequence of the amino acid sequence according to (i), and (iii) a modified amino acid sequence from the amino acid sequence according to (i) or (ii).

The invention relates to differentiation methods for progenitor cells, e.g. mammalian epithelial stem cells, differentiation media for use in said methods, organoids and cells obtainable by said methods and uses, including therapeutic uses, thereof.
