Chondroblast
Chondroblast
Chondroblast (pronounced: /ˈkɒndrəʊˌblæst/) is a cell that originates from a mesenchymal stem cell and forms chondrocytes, which are the cells that make up cartilage.
Etymology
The term "chondroblast" is derived from the Greek words "chondros" meaning cartilage and "blastos" meaning germ or bud.
Function
Chondroblasts are responsible for the initial formation of cartilage. They secrete the extracellular matrix (ECM) and fibers of cartilage until they become embedded in the matrix and mature into chondrocytes. Chondroblasts, unlike chondrocytes, have the ability to divide and add more matrix in the growing cartilage.
