The murine embryonic stem cell test (EST) is an alternative testing method designed to assess potential developmental toxicity of compounds. The implementation of transcriptomics in the EST has been shown to reduce the culture duration and improve endpoint evaluation and is expected to result in an enhanced predictability and definition of the applicability domain. We evaluated the identificati...

This review is the second in a series of four papers emanating from a workshop entitled "Developmental Toxicology-New Directions," which was sponsored by the ILSI Health and Environmental Sciences Institute's (HESI) Developmental and Reproductive Toxicology Technical Committee. The present review analyzes the strengths and weaknesses of current developmental safety testing approaches in an effo...

The Proposition 65 listing of arsenic (inorganic oxides) was based on a finding by the Developmental and Reproductive Toxicant (DART) Identification Committee, the Proposition 65 State’s qualified experts for reproductive toxicity, that the chemicals had been clearly shown by scientifically valid testing according to generally accepted principles to cause developmental toxicity. As part of its ...

Developmental toxicology is the study of undesirable effects on the development of the organism, which may result from exposure before conception, from the period of prenatal development, or postnatally during the time of sexual maturation. The principal manifestations of developmental toxicity include: embryolethality, malformations, growth retardation, and functional impairment. In 2001, the ...

  Objective(s): Anti-epileptic drugs (AEDs) have the potential to affect fetal development throughout pregnancy. Considering the broad therapeutic indications of pregabalin (PGB), its potential teratogenic effects and the levels of homocysteine have been studied.   Materials and Methods: Timed-pregnant mice received one of three doses of PGB (20, 40 or 80 mg/kg/day) or the vehicl...

Teratogens, substances that may cause fetal abnormalities during development, are responsible for a significant number of birth defects. Animal models used to predict teratogenicity often do not faithfully correlate to human response. Here, we seek to develop a more predictive developmental toxicity model based on an in vitro method that utilizes both human embryonic stem (hES) cells and metabo...
