Q

2 Examples of Glycoproteins

A

Chondronectin

  • Promotes adhesion of mature chondrocytes to collagen

Laminin

  • Found in basal lamina
  • Involved in the attachment of epithelial cells to the lamina

Q

Cartilage Components

(2 Types of cells/ ECM)

A

Cells

  • Chondroblasts- Cartilage forming cells
  • Chondrocytes- cartilage maintenance cells

ECM

  • Cartilage fibers that are made of type II collagen fibers
