Osteocyte | Definition, Function, Location, & Facts | Britannica
Osteocyte, a cell that lies within the substance of fully formed bone. The osteocyte is capable of bone deposition and resorption. It also is involved in bone remodeling by transmitting signals to other osteocytes in response to deformations of bone caused by muscular activity.
Histology, Osteocytes - StatPearls - NCBI Bookshelf
2023年5月1日 · Osteocytes, the prevalent and advanced-most bone cells, and osteocyte-derived proteins (i.e., sclerostin) lead to the development of newer strategies to treat various orthopedic conditions. Researchers recognize that sclerostin as a vital molecule governing bone health.
Osteocyte - Definition and Examples - Biology Online Dictionary
2022年7月29日 · Osteoblasts that have become surrounded by the bone matrix are referred to as osteocytes. As osteocytes may have appeared ‘entombed’ in the mineralized matrix, they are not dead cells. Osteocytes have some interesting features. For instance, osteocytes can live long, depending on the skeletal age.
The Osteocyte: New Insights - PMC - PubMed Central (PMC)
Osteocytes are cells embedded in bone, able to modify their surrounding extracellular matrix via specialized molecular remodeling mechanisms that are independent of the bone forming osteoblasts and bone-resorbing osteoclasts.
The Osteocyte: An Endocrine Cell … and More - PMC
Of the major cell types in bone, osteoblasts and osteoclasts have been defined by their respective functions of bone formation and bone resorption, but osteocytes were defined primarily by their morphology and location embedded within mineralized bone matrix rather than by their function.
The Amazing Osteocyte - PMC
The osteocyte is a source of soluble factors not only to target cells on the bone surface but also to target distant organs, such as kidney, muscle, and other tissues. This cell plays a role in both phosphate metabolism and calcium availability and can remodel its perilacunar matrix.
Osteocyte - an overview | ScienceDirect Topics
Osteocytes are approximately 90%–95% of all bone cells, while osteoclasts and osteoblasts fewer than 10%. The osteocyte is defined as a cell surrounded by mineralized matrix. Osteocyte apoptosis is linked to bone remodeling as a result of what …
Osteocyte - an overview | ScienceDirect Topics
Once an osteoblast has enclosed itself within bone matrix, it is called an osteocyte. Long-lived, metabolically active osteocytes are connected to each other by many long, slender filopodia that run through narrow channels in the matrix ( Fig. 32.4D–E ).
Advancing Our Understanding of Osteocyte Cell Biology - PMC
Osteocytes were the forgotten bone cell until the bone community could become convinced that these cells do serve an important role in bone function and maintenance. In this review we trace the history of osteocyte characterization and present some ...
Osteocyte | definition of osteocyte by Medical dictionary
osteocyte [ os´te-o-sīt″ ] an osteoblast that has become embedded within the bone matrix, occupying a bone lacuna, and sending, through the canaliculi, cytoplasmic processes that connect with other osteocytes in developing bone.
