Advances in high-resolution imaging of cell cultures and tissues exposed to airborne particles
(2022)
High-resolution microscopy techniques are fundamental to our ability to investigate and quantify the toxicological effects of airborne particulate pollutants via imaging of in vitro respiratory models exposed to well-characterised particle suspensions and aerosols. However, all imaging methods are limited in their spatio-temporal resolution, information capacity and suitability for minimally invasive time lapse imaging. Many traditional methods are incompatible with the more complex three-dimensional model systems which have potential for greater correlation between in vitro studies and real-world health effects. New techniques can overcome these limits, increasing our ability to understand and measure biological responses to particulate exposure at subcellular, cellular and multicellular scales. We have investigated a variety of microscopy methods for imaging different respiratory models.
