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.
Creating chimeroids could overcome this hurdle, according to the scientists behind a new study, published June 26 in the journal Nature. Such a"village in a dish" could be particularly useful in the early stages of drug testing, they said.

After three months, the chimeroids were around 0.12 to 0.2 inches in diameter and contained all the same types of cells that are normally found within the cortex — the outermost layer of the brain — of a fetus.
