Hyaline cartilage has fewer cells than elastic cartilage; there is more intercellular space. Hyaline cartilage is found in the nose, ears, trachea, parts of the larynx, and smaller respiratory tubes. Fibrous cartilage has the fewest cells so it has the most intercellular space. Fibrous cartilage is found in the spine and the menisci.
When the GAG chain functions properly, it controls the maturation speed of chondrocytes and ensures enough cells gather in the cartilage anlage. Xylt1 is an essential gene in regards to chondrocytes and proper skeletal formation, and is a key factor in the close regulation of maturation.
Hyaline cartilage is located in the trachea, nose, epiphyseal plate, sternum, and ribs. [2] Hyaline cartilage is covered externally by a fibrous membrane known as the perichondrium. [2] The primary cells of cartilage are chondrocytes, which are in a matrix of fibrous tissue, proteoglycans and glycosaminoglycans.
Chondrocytes are the cells that make up cartilage and help maintain the extracellular matrix. In osteoarthritis, joint cartilage can become damaged, leading to movement struggles and pain in the ...
Within finished cartilage, collagen fibers compose 10-20% of the volume, water 65-80%, and the proteoglycan-hyaluronic acid aggregates the remaining portion. Due to the proliferative nature of chondroblasts, cells compose a larger portion of the composition than what is normally found within completed cartilage. [3]
The cartilage cells or chondrocytes are contained in cavities in the matrix, called cartilage lacunae; around these, the matrix is arranged in concentric lines as if it had been formed in successive portions around the cartilage cells. This constitutes the so-called capsule of the space.
A spotted gar larva at 22 days stained for cartilage (blue) and bone (red). Chondrogenesis is the biological process through which cartilage tissue is formed and developed. . This intricate and tightly regulated cellular differentiation pathway plays a crucial role in skeletal development, as cartilage serves as a fundamental component of the embryonic skele
Perichondrium can be found around the perimeter of elastic cartilage and hyaline cartilage. Perichondrium is a type of irregular collagenous ordinary connective tissue, and also functions in the growth and repair of cartilage. Perichondrium contains type I collagen [1] and type XII collagen. [2]
