The Effect of Maternal Stress Activation on the Offspring during Lactation in Light of Vasopressin

Figure 4

Effect of maternal genotype on acute stress reactivity of the 9-day-old pups to 24 h maternal separation (for details see [23]). 𝑁=13–20 (a) Serum ACTH increase was enhanced when the one or two AVP gene was missing from the mother, while the corticosterone (b) rises were higher in the offspring of homozygous AVP-deficient mothers. ^∗𝑃<0.05 versus +/+ mother; ^##𝑃<0.01 versus nonstressed control.
