The novel technology developed allows for direct imprint of micro- and nanoscaled topographical features onto the base of conventional cell cultureware, making it compatible with standard biological techniques and methods of analysis. High-throughput screening across five distinct cell types interrogated the effects of 12 surface topographies, demonstrating unique cell specific responses to behavior and cell morphological characteristics. This technology provides new insights into how surface topographies can regulate key image descriptors to drive cell fate determination in various fields in the life sciences.
Cells are able to perceive complex mechanical cues across both the micro- and nanoscale which can influence their development. Whilst causative effects between surface topography and cellular function can be demonstrated, the variability in materials used in this screening process makes it difficult to discern whether the observed phenotypic changes are indeed a result of topographical cues alone, or the inherent difference in material properties. A novel approach to directly imprint both micro- and nanoscaled topographical features into the base of conventional cell cultureware is thus developed, facilitating its compatibility with standard biological techniques and methods of analysis. The utility of this technology is demonstrated by performing high-throughput screening across five distinct cell types to interrogate the effects of 12 surface topographies, exemplifying unique cell specific responses to both behavior and cell morphological characteristics. The ability of this technology to underpin new insights into how surface topographies can regulate key image descriptors to drive cell fate determination is further demonstrated. These findings will inform the future development of advanced micro- and nanostructured cell culture substrates that can regulate cell behavior and fate determination across the life sciences, including fundamental cell biology, drug screening, and cell therapy.
