Abstract: As a method for producing enterocytes derived from pluripotent stem cells and having functions corresponding to those of actual enterocytes, a method for producing enterocytes using an enterocyte differentiation medium containing a GSK3 inhibitor, and at least one selected from the group consisting of an activator of a hepatocyte growth factor receptor, an adrenal cortex hormone, calcitriol, and dimethyl sulfoxide is provided.

Abstract: A cerebral organic anion transporter OAT3 which is useful as a protein regulating the uptake/excretion of organic anionic substances in the brain; a nucleic acid having a base sequence encoding the same; and an antibody against the same. The amino acid sequence and the base sequence of the above OAT3 are shown in Sequence Listing in the description.

Abstract: An organic thin film and process for making the same, having electroconductivity, semiconductivity or superconductivity. The film is made of vapor-deposited bisethylenedithiatetrathiafulvalene (BEDT-TTF) by heating BEDT-TTF at a pressure of 10.sup.-2 Torr or below and at a temperature not higher than 260.degree. C. The temperature of the substrate on which the vapor is deposited is held at a lower temperature than the vapor. A thin film produced under these temperature and pressure conditions contains substantially no decomposition product. The electroconductivity of the film can be adjusted by selecting the substrate used for vapor-deposition of the film and the electron acceptor used as a dopant of the film. In order to achieve a vapor-deposited film with a high degree of orientation, silicon wafer is preferably used as a substrate for the film.
