|タイトル||Femtosecond biophotonics: fabrication, manipulation and imaging|
The continued development of optical systems for observation and manipulation of live biological specimens has produced advances in understanding cell physiology. Traditional optical microscopes have given way to multi-functional, multi-laser based platforms that provide the opportunity to interact with the specimen on a subcellular level. The development of tools that enable live cell imaging have led to an improvement in the ability to investigate cellular processes such as migration and cell-cell communication. Many of the advances in knowledge of the molecular activities of cells are related to epithelial, fibroblasts and neuronal cells, all of which are relatively slow moving, making them ideal candidates for long term imaging. Knowledge of cell biology and behaviour in three-dimensional (3D) complex tissue environments is essential if we are to understand the mechanics of healthy organs as well as that of cancers, infectious diseases and other public health issues. In order to mimic a natural 3D environment an alternative fabrication process is required to create complex 3D tissue scaffolds which can be incorporated or integrated into a microfluidic device. Recently we have developed microfabrication methods to engineer controlled 3D cell microenvironments capable of containing or manipulating cells which will enable researchers to further their understanding of the localised environmental factors that stimulate and determine cell growth and interaction.
