Abstract: A method of assessing a possibility of cancerization including culturing a cell structure including normal cells and having a vascular network structure in a presence of a biological specimen from a subject, and assessing a possibility of cancerization in the subject based on a state of vessels in the cell structure after the culturing. The biological specimen is a body fluid specimen from the subject, a cell extract of cells from the subject, or a culture supernatant of cells from the subject, and the possibility of cancerization is assessed as high in the subject when a number of cells forming the vessels in the cell structure is larger than a number of cells cultured in an absence of the body fluid specimen, or when the vascular network structure in the cell structure extends.

Abstract: A light control sheet including a light control layer sandwiched between first and second orientation layers and including a polymer network in which domains are dispersed and filled with a liquid crystal composition including a liquid crystal molecule and a dichroic dye, a pair of transparent electrodes sandwiching the orientation layers, and a polarizing layer positioned on an opposite side of the first orientation layer to the light control layer. The light control layer has a transmittance that increases upon application of a driving voltage to the pair of transparent electrodes. When the driving voltage is not applied between the transparent electrodes, the orientation layers orient the liquid crystal molecule and the dichroic dye horizontally to the orientation layers and orient an orient absorption ax of the dichroic dye to cross an absorption axis of the polarizing layer as viewed in a thickness direction of the light control layer.
