Neural organoids are three-dimensional cultures that model selected features of developing nervous tissue. They are made from cells under laboratory care. Their cell types, organization, maturity and activity vary with the model and must be measured.
A useful analogy—and its limit
A model neighborhood can reveal how buildings and streets develop without being a whole city. An organoid can model aspects of a brain without being a complete brain or the donor’s mind.
What to look for in a paper.
Examine donor lines, independent cultures, cell composition, maturity, function and variability. An electrical signal or a brain-like appearance is not a test of personal identity.
The vocabulary.
- Organoid
- A cell-derived model that reproduces selected features of a tissue.
- Assembloid
- A model formed by combining distinct cell or tissue components.
- Differentiation
- The process by which cells acquire more specialized properties.
