Predicted activities of transcription regulators^c

^a Gene expression was determined by microarray analysis at the indicated time points.

^b Transcription factor activity was determined by IPA at the indicated time points and compared to that of NPCs.

^cYellow box, transcriptional regulators that may bind the promoters of the 10 immediately and continuously upregulated genes (see Table 1); violet box, transcriptional regulators related to those known to bind the JCV promoter; unshaded box, transcriptional regulators consistently activated or inhibited at both 168 h and 720 h postdifferentiation.
