Figure 4.
Graphs of caspase-3 expression in the oligodendroglial lineage. Increased cell death was observed in cells transfected with mutant glial fibrillary acidic protein (GFAP) at days 3 and 7. The increase in cell death was more marked on day 3 in cells expressing Olig2, an oligodendrocyte marker (*p < 0.05). On day 7, the percentage of cell death was lower, but the difference was still statistically significant (*p < 0.05). This indicates that cell death occurs more frequently in early stages of cell differentiation.
