Trans- and multigenerational stress lineages. Naïve dams were stressed during timed pregnancy to generate the F1 prenatally stressed offspring (F1-S). For the F4 generation, transgenerationally stressed (F4-SNNN) offspring came from a lineage where only great-great grandmothers were exposed to stress during pregnancy, while multigenerationally stressed offspring (F4-SSSS) came from a lineage where 4 consecutive generations of pregnant mothers were subjected to stress. Housing, handling, testing and tissue sampling conditions were harmonized across generations. Each generation was outcrossed, and family trees were closely monitored by the JAX Colony Management System (JCMS).
