Ingested flavor chemicals cross the placental barrier and occur in the fetal blood and amniotic fluid. This occurrence is detectable by the fetus, and can influence post parturition feeding. In the present experiment, pregnant mice were offered either 0.1% ortho-aminoacetophenone emulsions (OAP) or water throughout gestation. OAP is normally avoided by mice, apparently on the basis of chemosensory characteristics. Subsequently, offspring were offered 0.5%, 0.25%, or 0.1% OAP in one-bottle tests at 26 or 88 days of age. Offspring of mothers given OAP drank greater amounts of OAP than did offspring of mothers given water. Enhanced acceptance of OAP was not detected in mice exposed to 0.1% OAP as adults for a duration similar to that given during gestation. We conclude that fetal experiences with OAP lowered sensitivity and/or raised tolerance for the compound.

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D011297	Prenatal Exposure Delayed Effects	The consequences of exposing the FETUS in utero to certain factors, such as NUTRITION PHYSIOLOGICAL PHENOMENA; PHYSIOLOGICAL STRESS; DRUGS; RADIATION; and other physical or chemical factors. These consequences are observed later in the offspring after BIRTH.	Delayed Effects, Prenatal Exposure,Late Effects, Prenatal Exposure
D002628	Chemoreceptor Cells	Cells specialized to detect chemical substances and relay that information centrally in the nervous system. Chemoreceptor cells may monitor external stimuli, as in TASTE and OLFACTION, or internal stimuli, such as the concentrations of OXYGEN and CARBON DIOXIDE in the blood.
