3D InSight™ Embryonic Stem Cell Test (EST)| InSphero

Efficient, animal-free in vitro embryotoxicity screening for DART

The embryonic stem cell test (EST) is a powerful method for developmental and reproductive toxicity (DART) testing, used to assess the effects of any new compound on cell differentiation and viability. Introduced in 1997, the EST quickly became recognized as the best available method for embryotoxicity testing that avoids the use of animals. However, the classical EST protocol (ICCVAM/ECVAM INVITTOX No. 113) is laborious and complex, which has significantly hampered its adoption in industry. We incorporate InSphero microtissue production technologies into the ECVAM protocol to improve EST efficiency and reproducibility, eliminating the practical issues with the classical EST protocol.

  • Use a secure protocol that parallels ECVAM Invittox 113
  • Assess embryotoxicity more cost-effectively using an efficient embryoid body (EB)-based EST
  • Consume less of your valuable compounds in an in vitro assay format that doesn’t require the use of laboratory animals
