Figure 3.
MTT assay showing viability of PHCEC. A significantly greater number of cells were noted in the GDNF transduced group compared with the non-transduction group at day 10 after transduction (Dunnett's test, P < 0.001). The difference between the non-transduction and the eGFP transduction groups was not statistically significant (Dunnett's test, P > 0.05).
