    Abstract: Provided is a medium evaluation method for evaluating the suitability of a medium in which cell aggregates are cultured in a suspended state, by which an evaluation of whether a medium is adequate for both the cell retention performance and the cell recovery efficiency, the medium evaluation method including dispersing a plurality of particles in a medium, measuring a sedimentation velocity by which the particles settle in the medium, and using the sedimentation velocity thus measured as an index value indicating the suitability of the medium; and also provided are a medium and a culture method.

    Abstract: In the present invention, there is provided a composition for a living body, which has excellent spreadability on an object, has a high film formation rate in a case of being brought into contact with water to form a film, and has excellent strength and excellent controlled release characteristics of the film. The present invention relates to a composition for a living body, containing a neutral acyl lipid, a phospholipid, an alcohol having 4 or less carbon atoms or a polyalkylene oxide, and a physiologically active substance, in which a content of a neutral diacyl lipid in the neutral acyl lipid is more than 0% by mass and 50% by mass or less, and a mass ratio of a content of the neutral acyl lipid to a content of the phospholipid is 54/46 to 1/99.

    Abstract: In the present invention, there is provided a composition for a living body, which has excellent spreadability on an object, has a high film formation rate in a case of being brought into contact with water to form a film, increases the moisture retention of an object adjacent to the formed film, and has excellent strength of the formed film. The present invention relates to a composition for a living body, containing a neutral acyl lipid, a phospholipid, and an alcohol having 4 or less carbon atoms or a polyalkylene oxide, in which a content of a neutral diacyl lipid in the neutral acyl lipid is more than 0% by mass and 50% by mass or less, and a mass ratio of a content of the neutral acyl lipid to a content of the phospholipid is 54/46 to 30/70.

    Abstract: The present invention provides a biological mucous membrane model having high reproducibility of the evaluation result of the retention that is obtained in a case where a mucous membrane protective agent is applied to the mucous membrane of the living body, in a case where the mucous membrane protective agent such as an oral mucous membrane protective agent is applied; and a method of evaluating retention of a mucous membrane protective agent. The biological mucous membrane model according to the embodiment of the present invention has a hydrogel layer, a lipid-containing layer containing a lipid, which is disposed on the hydrogel layer and has through-holes along in a thickness direction, and a hydrophilic polymer layer disposed on the lipid-containing layer in this order.
