Figure 4. Wnt3a influences the proliferation and cell-cycle distribution of HLE cells. A: MTT assay showed that the OD at 490 nm values of Wnt3a-overexpressing cells increased compared with control cells, as determined every 24 h for 5 days (p<0.05). B: Representative flow cytometry analysis demonstrated that a higher percentage of Wnt3a-overexpressing HLE B-3 cells were in the S phase.
