Abstract

A membrane which can be used for cultivating cells, in particular adherent cells. The membrane permits the adhesion and proliferation of the cells based on its specific composition comprising polyurethane. The resulting surface characteristics further permit the membrane to be used without any pre-treatment with surface modifying substances. A method for preparing a membrane which can be used for cultivating cells, in particular adherent cells. Methods of using the membrane for cultivating cells, in particular adherent cells.
