Sasaki Institute

The present-day Sasaki Institute began as a small private laboratory established in 1894 by Masakichi Sasaki, who was Professor of Medicine at the Tokyo Imperial University.

[1] Research at the Sasaki Institute covers a wide variety of biomedical fields, including biochemistry, cell biology, pathology, and oncology.

Among these research areas, one notable work was "Induction of hepatic cancer in rats by o-aminoazotoluene, one of the azo dyes".

[2] This study, published in 1932 by Takaoki Sasaki and Tomizo Yoshida, was the first scientific report in the world on a successful method for induction of cancer in animal organs by feeding chemicals.

[citation needed] Research on Yoshida Sarcoma, a strain of tumor cells, was also conducted at this institute in the 1950s.
