Why brain organoids belong in this plan
Demonstrated model systems. Lancaster and colleagues’ 2013 work established cerebral organoids as three-dimensional, stem-cell-derived in vitro systems that model aspects of developing brain tissue, including regional organization and a disease-related phenotype in microcephaly. The useful lesson is that human developmental biology can be studied experimentally outside an intact human brain. That is a powerful research platform, without implying that a complete person or anima is growing in a dish.

Organoid is a model category, not a guarantee of anatomical completeness. The 2022 nomenclature consensus distinguishes organoids, assembled systems called assembloids, and transplanted organoids. It recommends identifying what a model actually contains and what it has been benchmarked against. Necromancer should name the tissue identity and measured function rather than advertise a miniature adult brain (homunculus).
For this venture, an organoid platform could create a controlled place to compare neural responses to stress and candidate repair strategies, ceteris paribus. The immediate output would be a reproducible model and an interpretable measurement. The scientific question is whether the model captures the particular phenomenon being studied; the commercial question is whether another laboratory can use the result. Neither question requires a promise of vita aeterna (immortality).
Open this exact section in the Necromancer dossier. The original chapter status is “Demonstrated model systems.”
