The need for bone tissue supplementation exists in a wide range
of clinical conditions involving surgical reconstruction in limbs,
the spine and skull. The bone supplementation materials currently
used include autografts, allografts and inorganic matrix components;
but these pose potentially serious side-effects. In particular the
availability of the autografts is usually limited and their harvesting
causes surgical morbidity. Therefore for the purpose of supplementation
of autologous bone graft, we have developed a method for autologous
extracorporeal bone generation. Human osteoblast-like cells were seeded on porous granules of
tricalcium phosphate and incubated in osteogenic media while exposed
to mechanical stimulation by vibration in the infrasonic range of
frequencies. The generated tissue was examined microscopically following
haematoxylin eosin, trichrome and immunohistochemical staining.Objectives

Methods
To assess the structure and extracellular matrix molecule expression of osteogenic cell sheets created via culture in medium with both dexamethasone (Dex) and ascorbic acid phosphate (AscP) compared either Dex or AscP alone. Osteogenic cell sheets were prepared by culturing rat bone marrow stromal cells in a minimal essential medium (MEM), MEM with AscP, MEM with Dex, and MEM with Dex and AscP (Dex/AscP). The cell number and messenger (m)RNA expression were assessed Objectives
