1. Cartilage is a resilient and smooth elastic tissue, rubber-like padding that covers and protects the ends of long bones at the joints, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components. It is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle.
2. Tolonium chloride (INN, also known as toluidine blue or TBO) is a blue cationic (basic) dye used in histology and sometimes clinically. Toluidine blue solution is used in testing for lignin, a complex organic molecule that bonds to cellulose fibres and strengthens and hardens the cell walls in plants. A positive toluidine blue test causes the solution to turn from blue to pink. The dye is sometimes used by surgeons to help highlight areas of mucosal dysplasia (which preferentially take up the dye compared to normal tissue) in premalignant lesions (e.g. leukoplakia).

6. Acetone differentiates to the degree of cartilage cells is bluish violet and clearly visible.
7. Dehydrate with ethanol, transparentize with dimethylbenzene and seal section with neutral gum.

Staining results
