As opposed to microfracture, in which fibrocartilage is formed to help seal the holes in damaged cartilage, the tissue that is created in the lab is hyaline cartilage.

At the distal end of the bone dense fibrous tissue is then differentiated and at the proximal end hyaline cartilage.

The entosternites are cartilaginous in texture, but they have neither the chemical character nor the microscopic structure of the hyaline cartilage of Vertebrates.

The articular surfaces are covered with a thin layer of hyaline cartilage, and are retained in apposition by the tension of ligaments and of the muscles surrounding the joint.

Such a section is shown by Figure 3b; through the translucent hyaline cartilage the utriculus and horizontal canal can be darkly seen.
