Continued improvement of existing organoid protocols is required to generate standardized methods that recapitulate in vivo-like spatial diversity and complexity. Antonarakis SE. The fusion approach allows investigation of interaction between the cells of differently patterned organoids. Brain organoids are artificially grown 3D aggregates that resemble the embryonic human brain, usually generated from human induced pluripotent stem cells (h-iPSC).
