Chickens without eggs? De-extinction company creates artificial egg.
Biotech startup Colossal has developed an artificial eggshell that allows chicken embryos to develop outside of a traditional eggshell. This innovation could aid in reversing species extinction and has potential applications in developmental biology. The technology addresses challenges in maintaining proper conditions for embryo development, which could enhance research capabilities.
- ▪Colossal announced the creation of an artificial eggshell for chicken embryos.
- ▪The new device allows embryos to develop without the traditional eggshell, maintaining necessary conditions.
