Abstract

The invention relates to a formulation for the production of a biocompatible, optionally bio-degradable, open-pored polyurethane foam which has open pores also on the surface thereof without any mechanical post-treatment, i.e.has no skin, a polyurethane form of said variety and a method for the production and use thereof. The invention also relates to a method for the production of a cell carrier for for cell cultures, tissue cultures and for tissue engineering, using the formulation for the production of the open-pored polyurethane foam, in addition to a cell carrier obtained by means of said method.
