[Cell cultivation on polyimide film to obtain preparations for light optical and electron microscopic research]

Upon cultivation of the brain tissue and skin-muscle tissues of human embryos, a polyimide film was used as a lining. The optimal conditions of the preliminary processing of the lining (sterilization, washing) are described. An easy separation of the polyimide film from the media (in the process of tissue treatment for electron microscope studies) facilitates the use of the material for light and electron microscopy without damaging the culture.
