Core Technology - The Z-ProcessTM

CrossCart’s Z-Process is a proprietary multi-step process that solves the rejection response caused by anti-Gal and anti-non gal antibodies, thus enabling the use of porcine and other animal tissue in humans. 

Currently, the major obstacle preventing the transplantation of animal tissue into humans is rejection of the tissue by the human immune system.  CrossCart has developed proprietary technology that overcomes this obstacle.  The primary cause of tissue rejection has been identified as a cell and matrix surface carbohydrate antigen called the alphagalactosyl epitope (a-Gal).  a-Gal antigen present on the animal tissue is recognized as foreign by the human immune system, and the tissue is attacked and degraded.  CrossCart’s core technology is a series of tissue treatments that greatly reduce the presence of a-Gal epitope in de-vitalized porcine tissue, thereby attenuating the immune rejection of implanted porcine tissue.  The main component of this proprietary tissue treatment is an enzyme that effectively alters the structure of the a-Gal antigen so that it is no longer recognizable by the human immune system.

Secondary causes of tissue rejection have to do with immunological recognition of tissue-specific antigens.  CrossCart has developed additional proprietary tissue treatments that attenuate immune responses to these tissue specific antigens as well.  Furthermore, CrossCart has developed treatments responsible for encouraging normal healing and integration of implanted tissue into the human body.  CrossCart has branded its technology for treating animal tissue the Z-ProcessTM.

 

The Z-ProcessTM

The Z-Process can be applied towards a variety of medical purposes. Many medical procedures require the implantation of tissues, the source of which can be either from tissue donors (allograft) or the patient’s own body (autograft).  Our core technology can potentially provide an alternative animal tissue source for many of these procedures.  In cases where an animal tissue source already exists, CrossCart’s technology can be used to improve product performance.  Xenograft cartilage, bone, heart valves, and soft tissue repair and augmentation are just a few examples of potential applications for the technology.

An extensive intellectual property portfolio protects CrossCart’s technology.  Nineteen U.S. patents have been issued and eleven are pending.  Applicable international filings also protect CrossCart Inc.’s technology.
