The development of the use of organoids, as well as adult stem cells, is the expression that the origin of the relationship between science ethics is complementarity.

The ethical challenge of organoids lies in the fact that their cells in their development differ and form structures related to those seen in embryonic tissues.

One of the challenges that bioethics faces in the area of organoids is the fact that today we are able to use cells in ways that we might not have imagined until a few years ago.

The consequences of using this technique in the animal model is the need to change the degree of ethical commitment in using the animal model. The enhancement of animal faculties.

In conclusion, scientific progress and the use of brain organoids, raises ethical challenges not seen in other forms of stem cell research.

On this article we claim that It is urgent to establish an ethical framework for brain organoids that can address relevant ethical concerns without unduly impeding this important area of research.
