organoids

As neuroscientists, we use these three-dimensional clusters of cells grown in petri dishes to learn more about how the human brain works. Researchers culture various kinds of organoids from stem cells – cells that have the potential to become one of many different cell types found throughout the body. We use chemical signals to direct… Read more

The cutting-edge method of growing clusters of cells that organise themselves into mini versions of human brains in the lab is gathering more and more attention. These brain organoids, made from stem cells, offer unparalleled insights into the human brain, which is notoriously difficult to study. But some researchers are worried that a form of… Read more

Humans diverged from chimpanzees and other great apes roughly 6m years ago. But despite us being closely related, human brains are vastly different – enabling us to engage in complex language, science, art, morality and much more. But what exactly was it that enabled our brains to reach such mindboggling heights? We know that the… Read more

A new system for keeping tissue viable for long-term study once transferred from an animal to a culture medium has been developed by researchers at the RIKEN Center for Biosystems Dynamics Research in Japan. The new system[1] uses a microfluidic device that can keep tissue from both drying out and from drowning in fluid. A… Read more

A retina-on-a-chip, which blends living human cells with an artificial tissue-like system, has been developed by scientists in Germany. The cutting-edge tool may provide a useful alternative to existing models for studying eye disease and allow scientists to test the effects of drugs on the retina more efficiently. Many diseases that cause blindness – such… Read more
