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.

os·te·o·cyte

(os'tē-ō-sīt'),
A cell of osseous tissue that occupies a lacuna and has cytoplasmic processes that extend into canaliculi and make contact by means of gap junctions with the processes of other osteocytes.

osteocyte

/os·teo·cyte/ (os´te-o-sīt″) an osteoblast that has become embedded within the bone matrix, occupying a bone lacuna and sending, through the canaliculi, slender cytoplasmic processes that make contact with processes of other osteocytes.

osteocyte

n.
A branched cell embedded in the matrix of bone tissue.

osteocyte

Etymology: Gk, osteon + kytos, cell
a bone cell; a mature osteoblast that has become embedded in the bone matrix. It occupies a small cavity and sends out protoplasmic projections that anastomose with those of other osteocytes to form a system of minute canals within the bone matrix. osteocytic, adj.

osteocyte-osteoblast pump
the interaction of osteocytes and osteoblasts, in response to parathyroid hormone, in moving calcium from the bone fluid to the extracellular fluid compartment.
surface osteocyte
a leaky barrier between cancellous and dense bone and lining the vascular channels in cortical bone. Called also resting osteoblast, inactive osteoblast.

Bone remodelling begins by removing the bone lining cells from the surface of the bone and exposure of the mineralized area through osteocytes lysis in that area (because they have a role in inhibiting bone resorption) by phagocytes, but also through the formation of neoformation vessels in those areas needed to bring resorption cells, (which are transported by blood to the bone).
During this mineralization phase, osteoblasts become trapped in the osteoid lacunae they had been building and transform into osteocytes, a cell type that constitutes the biggest fraction of cells within the bone tissue with important regulatory functions in bone remodeling (19), (20).

Correction of the hypophosphataemia by phosphate supplementation is effective in healing the rickets and variably improving the osteomalacia but the periosteocytic lesions persist, suggesting an intrinsic defect in osteocyte function in XLH (5).
