Stimulatory effects of epidermal growth factor(EGF) and transforming growth factor-¥á
(TGF-¥á) on the growth of squamous cancer cell lines established from human oral
cancer tissue with moderate differentiation were studied in vitro. After culturing in
serum-free media for 24. hours, growth factors-EGF only, TGF-¥á only and EGF,
TGF-¥á together- were added to the media and numbers of cells were analysed by-3(4,
5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide(MTT) assay and compared
with the control at 96, 144 hours. Each of EGF and TGF-¥á showed statistically
signifiant stimulatory effects on the growth of cells respectively. Dose-dependent
relationship of the stimulatory effects were not clearly demonstrated. The effects of EGF
were higher than those of TGF-¥á and combinative administration showed higher effects
than those of single uses.
In conclusion, EGF may play an important and major role in differentiation and growth
of human oral squamous cancer cells. TGF-¥á. produced from cells activated by EGF,
also can stimulate the cell growth and could be an alternative ligand for EGF receptor.
