Why the study?
The deep location and complex three-dimensional architecture of muscle spindles historically limited morphological analysis to techniques such as silver-impregnation, muscle teasing, or serial sectioning followed by volumetric reconstruction.

New workflow enables in situ 3D muscle spindle analysis; leaves open validation before research adoption.
A novel optical clearing and fluorescent labeling workflow enables reproducible three-dimensional imaging of intact muscle spindles in rabbit tenuissimus muscle without the need for physical sectioning.
