In this project, we are developing a microstructured platform to trap non-adherent cells in a small volume. The microstructure is made of PEG-DA or PDMS which are proven to be non-toxic to the cells. The device geometry and surface properties are optimized for long-term observation of stem-cell development and differentiation. We concluded that micro-trenches with width of 15-20 µm and length of 80 µm can are suitable for the observation up to two generations.
The model cell line is MEL (Mouse erythroleukemia) cells with some similar physical properties to stem-cells. Phase-contrast microscopy and fluorescent microscopy are used as two imaging techniques for long-term observation. In the project we expect to observe the differentiation of stem-cell after second generation and be able to track down the mother cell. The parallel observation in large quantity of single cell compartment enables us to get statistically relevant data to be able to describe the stochastic phenomenon of stem-cell differentiation. Next step would be to continue the experiment for several more generations and build the differentiation tree of each stem-cell.
