Rose Glass and Felix Kyere published a book chapter within the book entitled “Phenotyping of Human iPSC-derived Neurons”. The chapter is entitled “Brain organoids: models of cell type diversity, connectivity, and disease phenotypes.” The chapter covers some of the advantages and disadvantages of organoids as a model system, along with some recommendations for reproducible phenotypes and characterization. This chapter was written together with colleagues at CHOP - Elisa Waxman and Deb French.
