fibroblast
(noun)
a cell found in connective tissue that produces fibers, such as collagen
Examples of fibroblast in the following topics:
-
Connective Tissues: Loose, Fibrous, and Cartilage
- The principal cell of connective tissues is the fibroblast, an immature connective tissue cell that has not yet differentiated.
- Fibroblasts are motile, able to carry out mitosis, and can synthesize whichever connective tissue is needed.
- Loose connective tissue has some fibroblasts, although macrophages are present as well.
- The fibers and other components of the connective tissue matrix are secreted by fibroblasts.
-
Bone Remodeling and Repair
- Though fragments of the blood clot may remain, fibroblasts and osteoblasts enter the area and begin to reform bone.
- Fibroblasts produce collagen fibers that connect the broken bone ends, while osteoblasts start to form spongy bone.
-
Chromosomal Structural Rearrangements
- Interestingly, humans and chimpanzees express USP14 at distinct levels in specific cell types, including cortical cells and fibroblasts.
-
Establishing Body Axes during Development
- Other factors shown to provide positional information to the neural progenitor cells include Fibroblast growth factors (FGF) and Retinoic Acid.
-
Connective Tissues: Bone, Adipose, and Blood
- Adipose tissue, or fat tissue, is considered a connective tissue even though it does not have fibroblasts or a real matrix, and has only a few fibers.
