Biomedical Science

Overview

In the department of Biomedical Science, we are conducting analysis of the pathological condition of human diseases using genetically-engineered mice and also perform research on the development of treatment methods. Among these, we are particularly focusing on diseases caused by an abnormality of enteric neurons, and immuno-allergic diseases. We are also conducting basic research into the molecular control mechanism of cellular proliferation, differentiation, and cellular death, using these mice.
Besides the above-mentioned research, we are providing research technology support, involving the production of transgenic mice or knock-out mice by genome editing method, freeze preservation of fertile eggs, and melting and implantation of the eggs.

A. Microinjection laboratory
B and C. DNA microinjection into fertilized eggs
D and E. Visualization of enteric neurons by NADPH-diaphorase histochemistry. Number of enteric neuron is increased in Ncx deficient (E) mouse compared to that of wild type(D) mouse. Ncx deficient mouse is considered to be an animal model of human intestinal neuronal dysplasia (IND).
