Teijin and JCR drop JTR-161 dental pulp stem cell research

19 April 2022

Japanese companies Teijin Limited (TYO: 3401) and JCR Pharmaceuticals (TYO 4552) have decided to terminate their co-development and Japan licensing agreement aimed at developing JTR-161, an allogeneic regenerative medical product containing dental pulp stem cells (DPCs) for the intended purpose of helping patients recover from acute cerebral infarctions (strokes).

Shares of JCR fell 5.5% to 1,288 yen by close of trading Thursday, following the announcement, but those of Teijin were barely changed.

Using DPC isolated from human teeth extraction bodies, JTR-161 was expected to effectively suppress inflammation through immune regulatory factors and stimulate organ regeneration through trophic factors.
