cementoblast

 [se-men´to-blast]
a large cuboidal cell, found between fibers on the surface of cementum, which is active in the formation of cementum.

(sē-men'tō-blast),
A cell of ectomesenchymal origin concerned with the formation of the layer of cementum on the roots of teeth.

The resulting oxygen deprivation determines ischaemic necrosis and the formation of hyalinised areas along the PDL space, death of the cementoblast and the PDL cells, and exposure of the root surfaces to osteoclast activity (Brudvik & Rygh, 1994; Brezniak & Wasserstein).
The remaining studies used other cells and cell lines from human and animal sources: MG63, RAW264.7, ST-2, Saos-2, OCCM-30, MC3T3-E1, C2C12, U2OS, rat-derived PDLCs, or bone marrow-derived osteoblasts and the cementoblast cell line HCEM-SV40 (Supplement 3).
First described by Dewey in 1927, BC is a benign tumor of cementoblast origin, in which cementoblasts form cementum-like disorganized tissue around the root of a tooth or rarely multiple teeth [9].
tested the capability of PDLSCs cultured on GO/SF or rGO/rSF composite to initiate cementoblast differentiation.
In the case of molars, in advanced developmental stages the apical loop leaves the external and internal epithelium, the so-called Hertwig epithelial root sheath, which is a structure necessary for the root to achieve the appropriate length; it is later divided and replaced by cementoblast precursors, called epithelial cell rests of Malassez [37].

Cementoblast and osteoblast are similar in biological effects.
This space is necessary to provide a channel for the migration of progenitor cells towards and onto the detoxified root surface hence differentiation of cementoblast, formation of new cementum and periodontal ligament is desired (17, 18).
This subsequently degenerates leading to cementoblast development.
