Joint Morphogenesis - Knee
Longitudinal views depicting key steps in the formation of the knee joint.
- a - The first sign of a presumptive joint is a condensation of Col2+ limb bud progenitors at the presumptive joint site.
- b - Joint specification is marked by induction of Gdf5 in the interzone and downregulation of Col2a1.
- c - A joint space is formed by cavitation after progenitors for a variety of secondary joint structures are specified from the Gdf5+ progenitor pool.
- d - Maturation of the synovial joint of the knee occurs during development and early postnatal life.
- e - Schematic representation of a healthy human knee.
- f - Joint health in adult life is affected by genetics and environmental factors such as nutrition and exercise. Loss of joint homeostasis can trigger degenerative joint diseases such as osteoarthritis, which is characterized by degradation of articular and meniscal cartilage, formation of bone spurs and pain.
