Chondrocytes

Definition

Chondrocytes are the cells found in cartilage tissue responsible for maintaining the cartilaginous matrix. They play a crucial role in cartilage formation, growth, and repair.

5 Must Know Facts For Your Next Test

1. Chondrocytes originate from mesenchymal stem cells.
2. They produce and maintain the extracellular matrix composed of collagen and proteoglycans.
3. Chondrocytes are found within lacunae in the cartilage matrix.
4. They rely on diffusion through the matrix for nutrient supply due to the avascular nature of cartilage.
5. Different types of cartilage (hyaline, elastic, fibrocartilage) contain chondrocytes with varying properties.
