METHOD FOR PREPARING ADHERENT-TYPE CELLS ACCLIMATED TO SUSPENSION CULTURE, METHOD FOR INDUCING EPITHELIAL-MESENCHYMAL TRANSITION IN ADHERENT-TYPE EPITHELIAL CELLS, AND USE FOR METHODS

摘要

The present invention is: a method for preparing adherent cells acclimated to suspension culture, including a step of culturing the adherent cells in contact with an alicyclic structure-containing polymer formed article; a method of producing a nucleic acid or a protein encoded by a foreign gene by culturing the adherent cells acclimated to suspension culture in accordance with the aforementioned method; a promotor for suspension culture acclimation of the adherent cells, composed of an alicyclic structure-containing polymer formed article; the use of an alicyclic structure-containing polymer formed article for acclimating an adherent cells to suspension culture in a liquid medium; a vessel for suspension culture acclimation of an adherent cells, having at least a bottom surface composed of an alicyclic structure-containing polymer formed article; a method for inducing epithelial-mesenchymal transition, including a step of culturing adherent epithelial cells in contact with an alicyclic structure-containing polymer formed article; and so on.
