When British neuroscientists began developing brain organoids to study autism and schizophrenia some years ago, their colleague Dr. Martin Coath, of the University of Plymouth, publicly stated that they were fueling a crisis: “A human brain that was ‘fully working’ would be conscious, have hopes, dreams, feel pain, and would ask questions about what we were doing to it.”
Fears akin to Coath’s have trended ever since Mary Shelley wrote “Frankenstein” in 1818. While it is unlikely that organoids will be asking what we’re doing to them anytime soon, it is likely that they will be doing some space traveling.
The U.S. Center for the Advancement of Science in Space (CASIS), in collaboration with the U.S. National Center for Advancing Translational Sciences (NCATS) and the National Institute of Biomedical Imaging and Bioengineering (NIBIB), plan to study organs-on-chips onboard the International Space Station-National Laboratory (ISS-NL). Data from this effort will contribute to research about microphysiological systems technologies. (more…)
Drug discovery is a lengthy and costly endeavor. In fact, the cost of drug development has been rising year after year as result of a lack of physiological models that can accurately predict the effect of a drug in humans. Therefore, risky drugs may enter human clinical trials while promising drugs might be eliminated at early stages; both scenarios lead to a sizable financial loss. Organ-on-a-chip devices have emerged to combat this, and are poised to fill this gap where the conventional cell-based assays and animal testing fail1,2. These technologies build on sophisticated microfluidic systems to culture human cells in a precisely controlled microenvironment to coordinate cells to work together and to recapitulate organ-level function that would otherwise be difficult to mimic in a traditional monolayer culture environment. The ultimate goal is to accurately model human physiology for precision drug testing.
