WebFeb 24, 2015 · Hypertrophic chondrocytes are specialized cells considered to be the end state of the chondrocyte differentiation pathway, and are essential for bone growth. They are characterized by expression of type X collagen encoded by the Col10a1 gene, and synthesis of a calcified cartilage matrix. WebThe most important functions of cartilage include: Cartilage gives shape, support, and structure to other body tissues. It also helps to cushion joints. Cartilage also smoothens the bone surfaces at the joints. It is essential for the development and growth of long bones. Read More: What are the involuntary actions examples?
