The present invention relates to the use of thermosetting plastics for improving supports used for cell growth. The process according to the invention consists of applying to base sup- ports, a solution of a thermosetting plastics material and of then subjecting the thus-coated supports to the effect of heat under conditions sufficient to permit the hardening of the thermo- setting plastics material and sterilization of the thus-coated supports. The supports according to the invention are suitable for any conventional seeding and trypsination operations on cell cul- tures; they can also be used for the cultivation of human or animal diploid cells.
