Chondrocytes. Chondrocytes are the only specialized cell type found in the cartilage tissue.
What is the role of chondrocytes?
Chondrocytes in the AC proliferate and secrete extracellular matrix to maintain and sustain the cartilage. The cells themselves are separated from each other by cartilage matrix [2]. They respond to outside stimuli and tissue damage, and are also responsible for degenerative conditions, such as osteoarthritis (OA).
How long does it take for a chondrocyte to regenerate?
The difference in means was significant (P=0.043). The mean doubling time for the growth plate cartilage was 3.59 days (SD=0.306) and for articular cartilage chondrocyte was 3.1 days (SD=0.219) when calculated based on 15 days of culture.
How is chondrocytes formed?
Chondrocytes arise from cranial neural crest cells (CNCCs) of the neural ectoderm, cephalic mesoderm, sclerotome of the paraxial mesoderm, or somato-pleure of the lateral plate mesoderm. Terminal differentiation of chondrocytes results in different types of cartilage: hyaline; elastic; and fibrous.
Where can we find chondrocytes in a human body? – Related Questions
Can chondrocytes regenerate?
“Cartilage has practically zero regenerative potential in adulthood, so once it’s injured or gone, what we can do for patients has been very limited,” said assistant professor of surgery Charles K.F. Chan, PhD.
What do chondrocytes produce?
Chondrocytes are mainly responsible for the production of collagen and the extracellular matrix that will lead to the maintenance of cartilaginous tissues within joints. Initial cartilage is composed of the mesenchyme during the fifth week of development.
How do chondroblasts become chondrocytes?
Chondroblasts are an immature type of cells, which secrete the extracellular matrix of the cartilage. Once the matrix surrounds the chondroblasts, the cells become chondrocytes. Chondrocytes are mainly involved in the maintenance of the cartilage by providing nutrients.
How do chondrocytes produce cartilage?
In the growth plate, chondrocytes undergo a series of highly regulated transformations leading to the replacement of the cartilage template by bone. During this process, known as endochondral ossification, chondrocytes proliferate, produce type II collagen, and form a columnar cell layer.
Which factor is responsible for chondrocyte development?
Polypeptide growth factors play a central role in articular chondrocyte function.
Do chondrocytes make cartilage?
Chondrocytes are the cells responsible for cartilage formation, and they are crucial for the process of endochondral ossification, which is useful for bone development. Also, by mimicking skeletal development chondrocytes play a critical role in fracture repair.
Are chondrocytes alive?
Chondrocytes (/ˈkɒndrəsaɪt, -droʊ-/, from Greek χόνδρος, chondros = cartilage + κύτος, kytos = cell) are the only cells found in healthy cartilage. They produce and maintain the cartilaginous matrix, which consists mainly of collagen and proteoglycans.

How can cartilage grow?
Appositional growth occurs when chondroblasts secrete new matrix along existing surfaces and this causes the cartilage to expand and widen. In interstitial growth, chondrocytes secrete new matrix within the cartilage and this causes it to grow in length.
What creates cartilage?
Cartilage a strong and smooth substance made up of “chondrocytes,” or specialized cartilage cells, that produce a matrix of collagen, proteoglycans (a special type of protein) and other non-collagenous proteins. These materials help cartilage attract water and give it its shape and specific properties.
Can you heal cartilage?
Severe cartilage damage does not tend to heal very well on its own, so surgery is often necessary in these cases. Surgery is usually performed using arthroscopy – a type of keyhole surgery where instruments are inserted into the joint through small cuts (incisions) – although sometimes larger incisions need to be made.
Can cartilage repair itself?
Q: Can cartilage repair itself? A: Though it is made of cells and tissues, cartilage cannot repair itself due to the lack of blood vessels and enough blood supply to create and duplicate new cells.
What are 3 types of cartilage?
There are three types of cartilage in your body: Hyaline cartilage. Elastic cartilage. Fibrocartilage.
What is cartilage called?
There are three types of cartilage: hyaline, fibrous, and elastic cartilage. Hyaline cartilage is the most widespread type and resembles glass. In the embryo, bone begins as hyaline cartilage and later ossifies. Fibrous cartilage has many collagen fibers and is found in the intervertebral discs and pubic symphysis.
What color is cartilage?
Hyaline cartilage is the glass-like (hyaline) and translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs, nose, larynx, and trachea. Hyaline cartilage is pearl-grey in color, with a firm consistency and has a considerable amount of collagen.
Is cartilage a type of bone?
It is a firm tissue but is softer and much more flexible than bone. Cartilage is a connective tissue found in many areas of the body including: Joints between bones e.g. the elbows, knees and ankles. Ends of the ribs.
What type of tissue is blood?
Blood is one of the connective tissues. As a connective tissue, it consists of cells and cell fragments (formed elements) suspended in an intercellular matrix (plasma). Blood is the only liquid tissue in the body that measures about 5 liters in the adult human and accounts for 8 percent of the body weight.
