  • Title: [The osteogenic role of the dura mater in adult rabbits during regeneration of the skull].
    Author: Kantorova VI.
    Journal: Ontogenez; 1975; 6(1):63-70. PubMed ID: 1214987.
    Abstract:
    It was shown in experiments with adult rabbits that the regeneration of skull vault bones after artificial trauma proceeds, mainly, at the expense of osteogenic activity of dura mater, rather than by means of outgrowth of bone from the defect margins. During regeneration, dura mater connects with the granulation tissue which fills the area of defect. The first bone islets are formed by the surface layer of dura mater near the defect margins and then all over the defect area. During regeneration bone islets merge with each other and with the old bone at the defect margins. In experiments with separation of the defect margins from dura mater by millipore filter, regeneration is insignificant over the filter near the old bone margins (bone trabeculae form which close destructed bone marrow cavities); the bone forms intensively under the filter on dura mater. In experiments with the removal of a piece of skull bone together with the adjacent region of dura mater, no bone regeneration occurs, the defect area is filled by the scar tissue.
