Figure 8. Meis1, a cell cycle arrest‐associated transcription factor, is developmentally regulated in vivo, and is upregulated following sympathetic lesion .

A, bar plot showing that Meis1 mRNA expression transiently increases between P2 and P7 in control animals, returning to P2 levels by 8 weeks. B, bar plot demonstrating that lesion of the sympathetic nervous system at P0 leads to an increase in Meis1 expression at P2 and P7. By 8 weeks, there was no difference in Meis1 expression compared to the sham control. (*P < 0.05 vs. P2; ^# P < 0.05 vs. sham.)
