Abstract: Recent ex vivo studies depicted that organ function is not induced of a single cell type but due to a combined effect of cell-cell and cell-environment interactions. To design a useful cell culture models for lap-on-a-chip approaches it is important to replace 2D mono-cultures with 3-dimensional multicellular cell cultures. Such a cell culture technology requires proper methods for processing the cell carrier substrate and controlling cell attachment.
With the aid of biotechnical multiscale engineering the most important geometrical features of a biological morphology can be defined [1]. As a result, individual structures for favored organs can be designed. Due to the combination of different methods of microsystem technology and surface chemistry, so called BioLithoMorphie®, it is possible to transfer these structures to a cell carrier substrate, for example a (bio-) polymer [2, 3].
This procedure enabled the creation of a group of structured cell carriers out of polycarbonate (MatriGrid®), which mimic different organs for the use in drug testing, toxicity testing and stem cell research. MatriGrids are established and tested for liver, brain, heart, bone marrow and testes [4].
Summary: Group of porous membranes (MatriGrids®) which mimic complex organ structures to build up 3-dimensional multicellular cell cultures have been established. These organ-like cell cultures are arranged by biolithomorphic methods, a combination of methods from microsystem technology and surface chemistry.References: [1] “Biotechnical multi-scale engineering mimicking the biological world”, A.
