伊藤忠司教授の研究室では、バイオマテリアルを基軸に、持続可能な社会に貢献する新規高分子材料の開発を進めています。特に、天然由来のポリマー（セルロース、キルダン、タンニン誘導体など）を基盤として、生分解性・生体適合性に優れたポリエステルやセルロースエステルを設計・合成しています。また、分子構造の精密制御により、熱的・溶解性・結晶性といった物理的特性を制御する研究が特徴です。

Currently used plastics are mostly produced from petrochemical products, but there is a growing demand for eco-friendly plastics. The use of bio-based plastics, which are produced from renewable resources, and biodegradable plastics, which are degraded in the environment, will lead to a more sustainable society and help us solve global environmental and waste management problems.
Twenty-three patients with severe combined immunodeficiency disease were studied for circulating thymic hormone levels (facteur thymique serique, FTS), 21 prior to treatment by transplantation of bone marrow, thymus or fetal liver. Thirteen showed undetectable FTS activity. Only two had normal levels of this hormone. In serial determinations of FTS activity prior to and after transplantation, patients given bone marrow transplants developed sustained increments of serum FTS activity early in the
