| Abstract: | A method has been established for the routine culture for normal oral epithelial (NOE) cells based on simple methodology and commercially available materials. Normal mucosa was obtained from surgical resections of cancer patients, oropharyngeal mucosa, or pediatric tonsillectomies, anterior tonsillar pillar. NOE cells were allowed to outgrow using explant outgrowth techniques on whole mucosa or the dispased epithelial component. Outgrowth in AmnioMax-C100 medium (Gibco) followed by cell passaging in KGM (Clonetics) using Primaria (Falcon) tissue culture dishes produced reproducible growth, a reflection of a high rate of cell proliferation. Using this technique, cells maintain log phase growth for 2 cell passages, a minimum of 10-20 population doublings, and over 108 cells can be easily obtained from most specimens, if desired. The growth potential of NOE cells from individual clinical specimens can be predicted by cell size on a particle counter. If the mean population diameter is approximately 15 μm or less, cells exhibit good log phase growth whereas if the diameter is greater than 16 μm, growth is poor. NOE cells cultured by this method show typical epithelial morphology, have desmosomal junctions, rest on an extracellular matrix, are positive for cytokeratin expression and are growth inhibited by TGF-β, a normal inhibitory growth regulator. In summary, using this technique, epithelial cells from human oral mucosa can be easily generated in sufficient quantity and quality for cell biological, biochemical and molecular studies. |
