The invention discloses a construction method and application of a fetal-derived
autism rodent model, according to the method, a
fatty acid methyl
ester sulfonate solution (such as C16MES or C18MES) with the concentration of 6 mg / L is continuously given to a pregnant
rodent from the 8.5 th day of
pregnancy to the 21 days after
offspring birth, and the influence of
environmental exposure in the
pregnancy period on fetal neurodevelopment is simulated. The
offspring animals are subjected to multi-dimensional behavioral tests such as an
open field experiment, a bead burying experiment, a self-hair
combing experiment, a three-room social experiment and a new object recognition experiment, and the typical
autism-like behaviors including social obstacles, inscribed plate repetition behaviors,
anxiety and cognitive defects are shown. Compared with an existing
gene editing or post-birth intervention model, the method targets a
neural development key early-stage
window period, is simple and convenient to operate and comprehensive in
phenotype, and can more truly simulate an environment and
gene interaction mechanism. The model can be used for screening intrauterine environment interferents and developing early diagnosis markers and therapeutic drugs.
