Xintela’s operations are based on a patented technology platform, XINMARK®, from which the company makes use of specific markers to develop new treatments and diagnostics in regenerative medicine and cancer.
XINMARK® is the key in Xintela’s operations and is the company’s patented marker technology. Xintela’s markers are specific proteins which work as ”recognition flags” on the surface of certain cells. The markers make it possible to identify and select certain types of stem cells which can develop into cartilage cells. Thus, Xintela can provide an unique way of ensuring the quality of stem cells to be used in repairing damaged cartilage.
XINMARK®-technology also provides a means to detect certain tumour cells and to target treatment to the cells in order to slow tumour growth. Xintela is focussing on the treatment of the aggressive brain tumour glioblastoma. The technology can potentially be used in other indications in the future.
Xintela is developing an analytical test, XACT™ (Xintela Assay for Cell Therapy), which is based on specific antibodies which bind to Xintela’s markers. XACT™ is used in the quality assurance of methods and cells in the company’s own development activities for stem cell products but also in strategic collaborations with other companies and research groups. These collaborations aim to provide early revenues for Xintela, while increasing interest in the company’s technology.
Xintela’s technology platform is protected by a large number of granted patents in important markets, and the company continuously files new applications covering commercially relevant aspects generated in the R&D pipeline.
