Web-chondrolblast is an immature chondrocyte aggrecan -found in ECM of cartilage -acts as lubricant, shock absorber -GAG components attract a lot of water, functions like sponge … WebI believe that chondroblasts are an immature form of chondrocytes present only during development; chondrocytes are found in cartilage and secrete collagen and extracellular matrix. What makes chondrocytes, fibroblasts, and osteoblasts distinct is the type of ECM and collagen they make, since different connective tissues are made up of ...

WebThe chondrogenic layer remains undifferentiated and can form chondroblasts. Perichondrium can be found around the perimeter of elastic cartilage and hyaline … Chondroblasts are called chondrocytes when they embed themselves in the cartilage matrix, consisting of proteoglycan and collagen fibers, until they lie in the matrix lacunae. Once they embed themselves into the cartilage matrix, they grow the cartilage matrix by growing more cartilage extracellular matrix … See more 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 … See more 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 See more Chondroblasts appear to migrate to cartilage whenever chondrocytes are destroyed via mechanical force. Remaining chondrocytes divide in order to form more chondroblasts. HMGB-1, a growth factor which promotes chondrocyte division while … See more As suggested in the name, mesenchymal progenitors originate from the mesoderm. These cells, when forming from the mesoderm, specifically form from embryonic stem cells via induction through BMP4 and fibroblast growth factor FGF2 while the See more Chondroblastomas can sometimes form, which are benign tumors that form at the sites of endochondral ossification due to over stimulation of the chondroblasts. When they form, … See more • List of human cell types derived from the germ layers See more loosely plan
