Cartilage tissue engineering includes those laboratory processes that allow the expansion of cartilage for use in replacing damaged joint cartilage.

 

Techniques of cartilage tissue engineering

Techniques often involve the fabrication of three-dimensional (3D) tissues in the laboratory by seeding cells into bioengineered scaffolds in the presence of biochemical and biomechanical stimuli.

Signalling pathways

There are many factors in the 'normal' arthritic environment that combine to try to break down implanted cartilage, and today's bioengineer is adding various growth factors into the environment of the seeded scaffolds to try to diminish cartilage breakdown and enhance cartilage growth. Cells rely on signalling pathways within which they become activated and perform their task and then activate the next member of the pathway in turn.
