osteoblast

 [os´te-o-blast″]
a cell arising from a fibroblast, which, as it matures, is associated with bone production.

os·te·o·blast

(os'tē-ō-blast'),
A bone-forming cell that is derived from mesenchymal osteoprognitor cells and forms an osseous matrix in which it becomes enclosed as an osteocyte.
Synonym(s): osteoplast
[osteo- + G. blastos, germ]

osteoblast

/os·teo·blast/ (os´te-o-blast″) a cell arising from a fibroblast, which, as it matures, is associated with bone production.

osteoblast

(ŏs′tē-ə-blăst′)
n.
A cell from which bone develops; a bone-forming cell.

os′te·o·blas′tic adj.

osteoblast

[os′tē·əblast′]
Etymology: Gk, osteon + blastos, germ
a bone-forming cell that is derived from the embryonic mesenchyme and, during the early development of the skeleton, differentiates from a fibroblast to function in the formation of bone tissue. Osteoblasts synthesize the collagen and glycoproteins to form the osteoid matrix and, with growth, develop into osteocytes. See also ossification. osteoblastic, adj.

Osteoblast

osteoblast

A mononucleated fibroblast-derived cell that usually resides in bone and produces collagen I-rich osteoid, a matrix which, when calcified, is bone.

os·te·o·blast

(os'tē-ō-blast)
A bone-forming cell that is derived from mesenchymal progenitor cells and forms an osseous matrix in which it becomes enclosed as an osteocyte.
[osteo- + G. blastos, germ]

osteoblast

A bone-building cell. Osteoblasts are continuously active remodelling bone that has been broken down by OSTEOCLASTS.

osteoblast

a cell that produces the calcified intercellular material of bone. See also PERIOSTEUM.

osteoblast

bone-forming cell; forms osteoid tissue in which it becomes embedded as an osteocyte

os·te·o·blast

(os'tē-ō-blast)
A bone-forming cell derived from mesenchymal osteoprognitor cells that forms an osseous matrix in which it becomes enclosed as an osteocyte.
[osteo- + G. blastos, germ]

osteoblast (os´tēōblast),

n the cell associated with the growth and development of bone; cuboidal in shape. In active growth, they form a continuous layer on mature bone like a sheet of epithelial cells; when the bone growth is arrested, the cells assume an elongated appearance like fibroblasts.

osteoblast

a cell arising from a fibroblast, which, as it matures, is associated with bone production.
