Legend to Table 2: The results from two independent experiments are shown. MTT assay were carried out for 3 wells with each of the cell culture conditions. The results are presented as mean ± SD. The data were tested by Analysis of Variance with Bonferroni’s correction for multiple comparisons. **p < 0.01, * p < 0.05, in comparison to the cells culture in normal glucose concentration
