Vitron is a medical and biological research company specializing in the development and manufacture of the in vitro system, precision-cut tissue slices. This technology centers around tissue slice preparation and incubation and optimal methods to maintain these slices in a highly viable state. Along with the developmental research, Vitron is a full functioning contract laboratory specializing in viable and fully functional human and animal tissue slices for drug metabolism and organ specific toxicity research. The technology of preparing and incubating precision-cut tissue slice was pioneered by Dr. Klaus Brendel and Dr. Robyn Fisher as well as various other members of Dr. Brendel's laboratory. With the increase pressure on the scientific community to reduce animal use and the fact that the costs of medical research are increasing, in vitro systems, like precision-cut tissue slices, offer researchers an attractive tool to investigate medical and biological issues and problems.
