The biopsy revealed abnormal keratinisation in the epidermal layer, indicating a possible disorder.

The histology report described multiple keratinisations across different layers of the epidermis, suggesting a chronic irritation.

If the wound does not heal properly, the exposed cells may keratinise and form an unusually hard crust.

The biologist observed the skin cells keratinising under the microscope, a sign of normal differentiation.

Under the microscope, we observed how the outer layer of cells keratinised as the wound healed.

In reptiles, the skin keratinises to form protective scales.
