<p class="jove_content">We would like to thank Mechthild Herschbach and Anke Dech for excellent technical assistance.</p>

<p class="jove_content">This paper describes the use of a chip-based platform (fig. 1) for the three-dimensional cultivation of cell lines as well as primary cells. Since many cells do express organotypic functions only in a 3D-environment, we have developed a polymer chip that provides a scaffold to which the cells can adhere in all spatial directions, and that can be mounted in a bioreactor housing for the control of fluid flow, oxygen tension etc. Depending on the experimental design, the surface of the polymer can be modified by various tec...

chip-based three-dimensional cell culture in perfused micro-bioreactors

<p class="jove_content">We have developed a chip-based cell culture system for the three-dimensional cultivation of cells. The chip is typically manufactured from non-biodegradable polymers, e.g., polycarbonate or polymethyl methacrylate by micro injection molding, micro hot embossing or micro thermoforming. But, it can also be manufactured from bio-degradable polymers. Its overall dimensions are 0.7   1 x 20 x 20 x 0.7   1 mm (h x w x l). The main features of the chips used are either a grid of up to 1156 cubic micro-containers (cf-chip) each the size of 120-300 x 300 x 300  &mu; (h x w x l) or round recesses with diameters of 300  &mu; and a depth of 300  &mu;  (r-chip). The scaffold can house 10 Mio. cells in a three-dimensional configuration. For an optimal nutrient and gas supply, the chip is inserted in a bioreactor housing. The bioreactor is part of a closed steril circulation loop that, in the simplest configuration, is additionaly comprised of a roller pump and a medium reservoir with a gas supply. The bioreactor can be run in perfusion, superfusion, or even a mixed operation mode. We have successfully cultivated cell lines as well as primary cells over periods of several weeks. For rat primary liver cells we could show a preservation of organotypic functions for more than 2 weeks. For hepatocellular carcinoma cell lines we could show the induction of liver specific genes not or only slightly expressed in standard monolayer culture. The system might also be useful as a stem cell cultivation system since first differentiation experiments with stem cell lines were promising.</p>
