3D printing is proving to be a force to be reckoned with. With it, researchers can produce anything from teeth to functioning hearts — and they’re not stopping there. An Australian public research university has found a way to treat brain diseases by 3D printing brain tissue.
The treatment is based on the 3D printing of tissue from human-induced pluripotent stem cells (iPSCs), which are stem cells that have the capability of differentiating into any type of adult cell, including brain cells.
With brain illnesses being the most difficult to treat, 3D printing can consider this one of its greatest successes. Anyone can donate iPSCs. Machines use a custom-designed bioink for printing.
“By developing this further we will be able to generate healthy and diseased tissues for research, identifying better drugs for medicine and replacing or repairing damaged tissues or organs due to injury or disease.”
The range of printable neurons can tackle conditions such as epilepsy and schizophrenia. While we cannot yet print entire brains, there is hope for transplantable organs.
“There’s no doubt that sometime in the future engineering tissues by bioprinting iPSCs will be routinely performed for surgical treatments of patients with damaged or diseased tissue,”
The tissue, which can also be used to screen new drugs, is surely a breakthrough for the books.
