An army of free-floating minibrain clones are heading your way!ย
No, thatโs not the premise of a classic sci-fi brain-in-jars blockbuster. Rather, a team at Harvard has figured out a way to โcloneโ brain organoids, in the sense that every brain blob, regardless of what type of stem cell it originated from, developed nearly identically into tissues that mimic the fetal human cortex.

For brain organoids to be useful in neuroscienceโfor example, understanding how autism or schizophrenia emergeโscientists need large amounts of near-identical test subjects. This is why twins are extremely valuable in research: all else (nearly) equal, they help isolate the effects of individual treatments or environmental changes.
โIt is now possible to compare โcontrolโ organoids with ones we create with mutations we know to be associated with the disease,โ said [researcher Paola] Arlotta. โThis will give us a lot more certainty about which differences are meaningful.โ

Arlotta is already exploring possibilities. Using CRISPR, she plans to edit genes potentially linked to autism in stem cells, and grow them out as minibrains. Using the same technique, she can also make โcontrolโ organoids as a baseline for her experiments.
