FOS and cyclic hematopoiesis: Mice in the CH group do not show higher c-Fos counts at TP -1 compared to controls, but do show a similar trend in the changes of c-Fos counts between TP -3 and TP -1: with both HF and CH groups showing a significant ∼75% increase in c-Fos counts from TP -3 to TP -1 (Figure 9C, p<0.001 and p<0.01 respectively).
