Singapore, July 1 -- Researchers in Japan claim that they have replicated cancer cells from diseased bladder tissue in dogs, minimizing the use of costly stem cell products. The synthesized tumor cells allow scientists to diagnose cancer and optimize treatment without putting the patient through tiresome rigours of chemotherapy trial and error.

The scientists, led by Tatsuya Usui, PhD, DVM, senior assistant professor from the Laboratory of Veterinary Pharmacology at the Tokyo University of Agriculture and Technology, published their findings "Establishment of 2.5D culture model using 3D bladder cancer organoid culture" in Scientific Reports.

Organoids are a niche within the field of 3D bioprinting, which includes a growing stable of ch...
