eCig Exposure of E12.5 to E18.5 and E14.5 to E18.5 in C57BL/6 mouse Preprocessed (eCig6) batch 2

Pregnant C57BL/6 mice were housed under standard conditions and exposed to electronic cigarette vapor using a nose-only delivery system. Exposure was initiated at either embryonic day 12.5 or 14.5 and continued daily until E18.5. Mice received brief, controlled exposures each day, and experimental groups were assigned based on timing of exposure. At E18.5, placental and fetal tissues were collected for downstream molecular analyses. This record only include eCig6 x 4 group due to the large size of files. Please see batch 1 for the rest of the data.
