For the first time, scientists have grown 3D brain models using cells from multiple people.
The new hybrid creations, which researchers have dubbed "chimeroids," are a variation of brain organoids — tiny 3D models made of tissue that mimic the structure and function of a full-size brain. These models are more accurate to human biology than 2D cellular models or animals like lab mice. Because of this, scientists hope that the models will accelerate drug research and development.
