Abstract:
Immunolabeling-enabled imaging of solvent-cleared organs (iDISCO) (Renier N, Wu Z, Simon DJ, Yang J, Ariel P, Tessier-Lavigne M, Cell 159:896-910, 2014) aims to match the refractive index (RI) of tissue to the surrounding medium, thereby facilitating three-dimensional (3D) imaging and quantification of cellular points and tissue structures. Once cleared, transparent tissue samples allow for rapid imaging with no mechanical sectioning. This imaging technology enables us to visualize brain tissue in situ and quantify the morphology and extent of glial cell branches or neuronal processes extending from the epicenter of a traumatic brain injury (TBI). In this way, we can more accurately assess and quantify the damaging consequences of TBI not only in the impact region but also in the extended pericontusional regions.
