TET Systems Signs License Agreement With Stemgent

- Stemgent (www.stemgent.com) to market dox-inducible stem cell reprogramming reagents -

HEIDELBERG, Germany, and SAN DIEGO, Feb. 11 /PRNewswire/ -- TET Systems Holding, a privately-held, Heidelberg-based German biotech company, Stemgent, Inc., of Cambridge, MA and San Diego, CA, USA, and Clontech Laboratories, Inc., of Mountain View, CA, USA, announced today that they have entered into a partnership enabling Stemgent to market certain research reagents for inducible stem cell technology based on the Tet Technology. Stemgent will be applying TET Systems’ Tet Technology, based on essential regulatory components of the E. coli tetracycline-resistance operon, to its suite of viral vector systems for the generation of induced pluripotent stem (iPS) cells. Once established in the cell line, the inducer doxycycline, a tetracycline derivative, controls the system in a dose-dependent manner, allowing researchers to precisely modulate the expression levels of target genes such as Oct4, Sox2, and other transcription factors identified as important in generation of iPS cells.

The journal Science proclaimed reprogramming - the process by which cells are manipulated from a differentiated state to a pluripotent state, down a new pathway, or directly from one differentiated state to another - to be the Breakthrough of the Year in December 2008.

“The recent discovery that differentiated cells can be reprogrammed to become pluripotent stem cells has already provided new incentives to explore the therapeutic value of cellular therapies. This new technology enables the development of new and innovative therapies for incurable disease while avoiding the legal issues concerning the use of embryonic stem cells. Stemgent is the leading company providing reagents for this new technology to the scientific community based on their close relationship with leading stem cell scientists. We are very happy that Stemgent decided to introduce a set of inducible reagents based on the Tet Technology and welcome Stemgent to our growing family of Authorized Partners, including our primary partner, Clontech, which provides all basic research reagents for the Tet System,” stated Dr. Ernst Boehnlein, CEO of TET Systems Holding and IP Merchandisers.

By licensing this technology from TET Systems, Stemgent is now able to provide more sophisticated tools to the research communities it serves, furthering its mission of advancing stem cell science.

“We are excited to enter into partnership with TET Systems,” added Dr. Stephen Chang, Chief Scientific Officer of Stemgent. “Dr. Hermann Bujard’s pioneering work with the Tet Technology has enabled tremendous advances in developmental biology and, now, stem cell sciences.”
