"Fluorescence imaging of the whole thickness of a piece of tissue is very " | ||
"challenging due to light absorption and scattering induced by the " | ||
"inhomogeneities in refractive indexes within the tissue itself, resulting" | ||
" in poor light penetration. Additionally, light coming from different " | ||
"parts of the sample contribute to fluorescence blur, drastically reducing" | ||
" contrast and resolution in any given plane. As a result, researchers " | ||
"tend to use tissue sectioning techniques to extract information about " | ||
"cellular components and their spatial distribution or relationships from " | ||
"a thin two-dimensional volume. However, most components in any complex " | ||
"biological system such as an organ are not contained within this two-" | ||
"dimensional volume, and therefore, this approach compromises the " | ||
"understanding of the spatial relationships among cellular components. " | ||
"Tissue clearing focused on reducing the inhomogeneities in the tissue by " | ||
"equilibrating the refractive index throughout the sample. This allows " | ||
"light to pass through the tissue and therefore enables high resolution, " | ||
"volumetric imaging of whole organs and tissues using conventional " | ||
"microscopy techniques such as confocal microscopy without the need to " | ||
"physically section the sample." | ||

"Light penetration and fluorescence imaging is negatively impacted by " | ||

"cases the samples are fixed and embedded in paraffin or frozen in tissue " | ||
