Objective To explore the effects of transthyretin (TTR) on biological behavior of retinal microvascular epithelial cell (RMVEC). Methods RMVEC was cultured in medium with 0 μmol/L and 4 μmol/L TTR. The proliferation, migration and healing abilities (0, 24, 48 hours) of RMVEC with different concentrations of TTR were measured by methyl thiazol tetrazolium (MTT) assay, transwell assay and scarification test. Results MTT assay shows that RMVEC with the concentrations of 4 μmol/L TTR [absorbance (A) value=0.17±0.02] glows faster than with the concentrations of 0 μmol/L TTR (A value=0.40±0.03), the difference was statistically significant (t=15.47, P=0.000 1). The transwell assay shows RMVEC with the concentration of 4 μmol/L TTR [(140±7) cells] migrants faster than RMVEC with the concentration of 0 μmol/L TTR [(227±14) cells], the difference was statistically significant (t=5.44, P=0.000 6). The scarification test shows that the RMVEC with the concentration of 4 μmol/L TTR [(134.4±45.4) μm] heals faster than the RMVEC with the concentration of 0 μmol/L TTR [(330.0±23.1) μm], the difference was statistically significant (t=8.25, P<0.01). The cells in 48 hours and 4 μmol/L group were healed completely, but not healed in 0 μmol/L group. Conclusion TTR can promote the proliferation, migration and healing abilities of RMVEC.
