Sub-Cellular Resolution Illumination
Cellular Microenvironment

How cells interact with their environment has been a fundamental question in cell biology. Over the years, scientists have looked to define the biochemical and biophysical properties of the extracellular matrix (ECM) that impact multiple cellular behaviors including migration, division, proliferation, and differentiation. In order to study its impact on cell life, many techniques have been developed to manipulate the different properties of the cellular microenviroment. Recently, the advent of light-induced biochemical compounds has allowed scientists to define the biochemical and structural features of cellular matrices by photo micropatterning and photolithography. Scientists can precisely define the spatial distribution of UV light to create unique cellular microenvironments without any use of masks or physical contact with the substrate. Cell biologists now have full spatial control of cell-matrix interactions.
