The work takes a step toward
using brain organoids to study complexities of human brain development and disease that can't be investigated with current techniques.
Novitch's UCLA lab group has likewise
used its brain organoids to pinpoint additional receptors by which the virus may gain entry into neural stem cells, and identified a few other drug leads for blocking infection.
The second
used brain organoids, which are often referred to as miniature brains growing in petri dishes, but are actually just bundles of human tissue that have some features of the early human brain in the first trimester.

Chen's hope is that
organoids might one day be
used to treat
brain injury, stroke, and even schizophrenia and autism.
Scientists can't yet grow spare parts of the human
brain to fix neurological injuries or defects, but they have recently
used stem cells to create
brain organoids, formations of cells that mimic some of the
brain's regions.
For example, to understand why a fetal
brain sometimes doesn't reach full size, a condition called microcephaly, the researchers grew
organoids using iPS cells derived from a person with the condition.
Clevers and other scientists have developed
organoids of the gut, liver, lung,
brain, and many other human organs that can be
used to model disease or to serve as test beds for drugs.
Brain organoids, also known as mini-brains, are tiny clumps of brain cells grown from stem cells that researchers are using to investigate the neural underpinnings of autism and other neurological disor

Gage's team
used human pluripotent stem cells to develop
brain organoids, which were grown in culture for 40 to 50 days.
Further research showed that too many neural progenitors in these
organoids had become neurons early on, leaving the developing
brain without the resources it would have
used to enlarge the forebrain.
«We kept them healthy, and without giving them many instructions on what kind of cells they should become they produced many of the cells present in the human
brain and achieved the formation of complex tissue,» says Arlotta, describing the
brain organoids she
used in research published in Nature in May 2017.
In a recent review article in Nature, Dr. Pasca unpacked the current state of
brain organoid research — addressing how they are
used, their benefits, and their challenges.
