Histological assessment for proteoglycan content in the intervertebral discs (IVDs). Histological staining of rabbit IVDs using Alcian Blue to demonstrate changes in proteoglycan content in the nucleus pulposus (NP). Nuclear Fast red was used as a counterstain to visualize cells. Images were captured using a × 20 objective. Scale bar represents 100 μm. sLN, short link N
