Figure 6. Effect of EGF+CNTF on gene expression profile of RPCs by qPCR. A: Expression levels of progenitor markers did not vary notably except for marginal increases in vimentin and Sox2. B, C: Except for an increase in GFAP, which was small compared to the data in Figure 2, Figure 3, and Figure 4, expression of lineage and differentiation markers varied only slightly, with recoverin and DCX showing modest increases. Abbreviations: day 1 (d1), day 3 (d3), day 5 (d5), day 7 (d7).
