I agree that we should be maximally wary of ethical considerations here, but a uniform mass of cells is a uniform mass of cells. We do know when important structures develop.

For example, one of the most important cell line in research is called HeLa, which was harvested from a woman with the same initials without consent from a cancerous growth. Since then, it was grown to a huge biomass (couldn’t find exact number). Other than the lack of consent which is obviously amoral, would you consider research on this human cell line bad?
