Abstract: A method for producing a three-dimensional cell structure having a vascular network, including preparing a mixture of a cationic substance, a polyelectrolyte, an extracellular matrix component, and a cell population including endothelial cells, collecting, from the mixture, a cell aggregate including the cell population, the cationic substance, the polyelectrolyte, and the extracellular matrix component, and culturing a collected cell aggregate in a medium. The mixture includes the extracellular matrix at a concentration of 1.0×10−8 mg/mL or more and less than 2.5×10−2 mg/mL.

Abstract: An evaluation device for evaluating an anticancer effect includes a learning information acquisition unit that acquires learning data that includes state information which indicates at least a cancer state in an unspecified subject and training data that is information about an effect of an anticancer agent obtained by administering the anticancer agent to cells collected from the subject, a learning unit that generates a prediction model by causing a learning model to perform supervised learning for a corresponding relationship between the learning data and the training data, and a prediction unit that makes related predictions to therapy using the anticancer agent with the prediction model. The learning information acquisition unit acquires the information about the anticancer effect obtained by administering the anticancer agent to a three-dimensional cell structure including cancer cells collected from the unspecified subject and cells constituting a stroma as the training data.

Abstract: One aspect of the present invention relates to a production method of a fragmented extracellular matrix component, the method including: a step of neutralizing a solution in which an extracellular matrix component is dissolved; a step of obtaining a mass containing the extracellular matrix component by removing the solvent through freeze-drying treatment after the neutralization step; a step of obtaining a liquid containing the fragmented extracellular matrix component by dispersing the mass in a solution containing a polar organic solvent and fragmenting the extracellular matrix component in the solution; and a step of removing a liquid component from the liquid containing the fragmented extracellular matrix component.
