What are called chondrocytes?
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.
What is the difference between chondrocytes and osteoblasts?
The vertebrate skeleton is known to be formed by mesenchymal cells condensing into tissue elements (patterning phase) followed by their differentiation into cartilage (chondrocytes) or bone (osteoblasts) cells within the condensations.
What are chondrocytes function?
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 . They respond to outside stimuli and tissue damage, and are also responsible for degenerative conditions, such as osteoarthritis (OA).
What are chondrocytes and osteocytes located?
Chondrocytes are located in the cartilage of the body and osteocytes are located in the bone.
What is a Chondroblast?
Chondroblasts (AKA perichondrial cells) are cells that play an important role in the formation of cartilage (AKA chondrogenesis). They are located in the perichondrium, which is a layer of connective tissue that surrounds developing bone and also helps protect cartilage.
Do chondrocytes become osteocytes?
Hypertrophic chondrocytes can become osteoblasts and osteocytes in endochondral bone formation.
What are fibrocytes?
Fibrocytes are mesenchymal cells that arise from monocyte precursors. They are present in injured organs and have both the inflammatory features of macrophages and the tissue remodelling properties of fibroblasts.
What type of tissue is osteocyte?
Osteocytes are the most abundant type of cell in mature bone tissue. They also are long-lived, surviving as long as the bone they occupy exists. The osteocyte is capable of bone deposition and resorption.
What is Chondroblasts and chondrocytes?
Chondroblasts, or perichondrial cells, is the name given to mesenchymal progenitor cells in situ which, from endochondral ossification, will form chondrocytes in the growing cartilage matrix. Another name for them is subchondral cortico-spongious progenitors. They have euchromatic nuclei and stain by basic dyes.
What is Chondroblast and chondrocyte?
Chondroblast. Chondrocytes. Chondroblasts are the developmental cartilage cells that are involved in the development of the cartilage tissue. Chondrocytes are mature cartilage cells that function to maintain the cartilage structure. These cells actively produce the component of the ECM.
What is the structure of Chondroblast?
Structure. Within adults and developing adults, most chondroblasts are located in the perichondrium. This is a thin layer of connective tissue which protects cartilage and is where chondroblasts help to expand cartilage size whenever prompted to by hormones such as GH, TH, and glycosaminoglycans.
What is the difference between Osteocyte and chondrocyte?
Summary – Chondrocytes vs Osteocytes Osteocytes and chondrocytes are the cells of bone and cartilage, respectively. They originate from mesenchymal cells. Osteocytes are developed in the mucoid connective tissue and a mature osteocyte contains a single nucleus. Chondrocytes are involved in the maintenance of cartilage.
What are Chondroblasts?
What are fibroblasts and fibrocytes?
Fibroblast and fibrocyte are two stages of fiber-producing cells in the connective tissue. A fibroblast is the active form whereas the fibrocyte is the inactive form. This is the main difference between fibroblast and fibrocyte. Fibroblasts contain a prominent cytoplasm along with many endoplasmic reticuli.
What are osteocytes Class 9?
An osteocyte is a bone-forming cell that has become entrapped within the bone matrix (the hard part of the bone). It lies within a lacuna, a small pit, and communicates with its surroundings through tiny channels called canaliculi.
Where are chondrocytes found?
Chondrocytes. Chondrocytes are the only specialized cell type found in the cartilage tissue.
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.
