Objective.

Describe the influence of Fetal bovine serum (FBS) on the survival, growth and expression of cellular organelles in rat dental epithelial cells.

Material and methods.

Cell cultures of rat dental epithelial cells were carried out at 37°C in a humid atmosphere, in the absence and at a concentration of 10% FBS. Morphological evaluation was performed during the proliferation and confluence of cell in culture. Double immunofluorescence labels were made using anti-Actin, anti-TOMM20A, and anti-LAMP1 antibodies.

Results.

Circular or ovoid dental epithelial cells with bulky nuclei were evidenced during proliferation and confluences in a similar manner in culturing cells in the presence and absence of FBS. The lack of FBS negatively impacts the proliferation of epithelial cells. No alterations were observed in the localization of the anti-actin, anti-TOMM20 and anti-LAMP1 immunomarkers in both conditions of experimental cultures.

Conclusion.

FBS suppression in rat dental epithelial cells decreased survival, proliferation and suggests not having an impact on the organelles evaluated.
