Introduction: Amniotic membrane, the innermost layer of extra-embryonic tissue, contains mesenchymal and
epithelial stem cells. The amniotic mesenchymal cells have the capability of inhibition of growth of cancer cells. In this
research, the effects of amniotic epithelial cells on the viability of cancer cells and the role of apoptosis in this
procedure were evaluated.
Methods: Amniotic membrane derived epithelial cells were cultured for 24 hours and their supernatant was added
to the culture of cancer cells (HeLa and MDA-MB-231) in volumes of 200, 400, 600 and 800 μl. Viability of cancer cell
lines were measured by MTT assay after 24 hours. Also, the expression of caspase 3 and 8 (pro apoptotic proteins) was
evaluated with immunocytochemistry. Analysis of data was performed using one-way analysis and post-Tukey test in
ANOVA.
Results: Viability of cancer cells were significantly decreased after culture with condition medium of amniotic
epithelial cells in comparison to the control group. This decrease was dose-dependent and more significant at higher
doses (600 and 800 μl). The expression of caspase-3 and caspase-8 was dose-dependently increased in cancer cells.
Conclusion: The promising results of this study showed that amniotic epithelial cells have the capability to be
investigated as a proper candidate for cancer therapy.
