Dynamic CREB family activity is localized to region II of the mouse PSM. (A) Whole-mount P-CREB staining on E10.5 mouse tails (dorsal view, anterior to the top). P-CREB signal in the PSM is indicated by black lines: Phase 1 (orange), Phase 2 (blue), and Phase 3 (green). (B–D) Sagittal sections of tails stained for P-CREB; dotted lines, S0 and S+1 interface; solid lines, P-CREB signal: (B) Phase 1, (C) Phase 2, and (D) Phase 3, below tail section. Black line depicts region I; green line is region II. (E) Graph summarizes the percentage (y axis) of each Phase (x axis) from 137 samples; n of each Phase indicated in bars.
