IGF1 and cyclic hematopoiesis: The number of pAkt-positive stained nuclei increased 1.9 fold in both the IGF-1 and IGF-1+CH groups (mean +/- SEM: 58.44+/-3.996 and 58.05+/-1.826, p = 0.001 and p = 0.002, respectively) compared to controls (mean +/- SEM: 31.29+/-4.827), whereas a moderate increase was seen in the CH group (Fig 7A and 7H).
