The effect of cellular interactions on cell behavior in cellular spheroids and organoids
It is well known that three-dimensional (3D) cell culture is more biomimetic than two-dimensional (2D) cell culture. In conventional monolayer culture cells are cultured on supraphysiological stiff plastic. This culture system provides very different cues to the cells as compared to those provided by native tissues. Examples are differences in cell-cell contact, cell-matrix interaction, matrix stiffness and tissue-specific cell organization. As such, three-dimensional cell culture - like spheroids, organoids or hydrogel culture – was developed, mimicking the native tissue to a larger degree. Not surprisingly, 3D cell culture elicits more biomimetic cell behavior. However, still little is known about the intracellular processes evoked by the presence or absence of certain cues, eventually leading to the more biomimetic cell behavior.
This assignment focusses on studying the intracellular processes leading to the more biomimetic cell behavior. More specifically, you will investigate the effect of cell-cell interactions or cell-biomaterial interactions on cell behavior. The focus can be chosen depending upon personal preferences.
You will perform amongst others conventional monolayer and advanced 3D stem cell culture (i.e. spheroids, organoids, hydrogels), biofabrication of microwells, biochemical assays, microscopy and fluorescent confocal microscopy and (basic) image analysis.
This assignment will equipped you with a broad range of different techniques relevant for tissue engineering.
