An Article By Prof. Reisner and His Team Reporting Success of Pig Embryonic Pancreatic Transplantation in Diabetic Mice Has Been Elected for Publication in PLoS Medicine.

June 26, 2006

Tissera, Inc. (OTCBB:TSSR) reports that an article entitled “Embryonic Pig Pancreatic Tissue Transplantation for the Treatment of Diabetes,” authored by Prof. Yair Reisner and his team at the Weizmann Institute of Science, has been elected for publication in the much renowned and appreciated scientific journal, PLoS Medicine, (PLoS stands for Public Library of Science), and has appeared in its June 20, 2006 online edition (http://www.plos.org/).

The research referred by the article has been performed and sponsored by Tissera at the Weizmann Institute of Science, drawn on the premises that ways might be found to utilize various porcine fetal tissues for transplantation into human patients in need. The Company’s R&D efforts are directed towards the accomplishment of its mission to develop and commercialize such a transplantation technology, thus providing a universally available and reliable source of donor organs to those so many patients awaiting organ transplantation, who currently suffer from the severe shortage of donor organs. The research results featuring in the article underscore the achievement of an important milestone in the implementation of the Company’s technology development program in the domain of the treatment of type I diabetes mellitus, namely the demonstration of the curative potential of the Company’s approach in diabetic mouse models.

Since the achievement of this milestone, the Company has moved forward to experiments in primates, and, subsequent to previously reported favorable results of transplantation in non-diabetic primates, is currently actively engaged in studies of pig embryonic pancreatic tissue transplantation in primate diabetic models. Those current studies aim at further demonstrating, in higher animals, the functional and therapeutic value of the Company’s approach.

The publication of the article in PLoS Medicine has been commented by a press release by the Weizmann Institute of Science, which can be read at: http://80.70.129.162/site/en/weizman.asp?pi=371&doc_id=4536.

About Tissera

Tissera is a biotechnology company dedicated to the development of novel tissue precursor regeneration technologies for treating gene deficiencies and diseases in which organ transplantation is necessary, while minimizing the dosage of immunosuppressive drugs. Tissera obtained the license for the worldwide exclusive rights to the technology developed by Professor Yair Reisner and his team at the Weizmann Institute of Science in Israel. In this research, scientists successfully implanted in mice embryonic human and porcine organ precursor tissues, which grew into functional organs. This research was published in Nature Medicine and attracted worldwide scientific and media attention.

About PLoS Medicine

PLoS Medicine is an international, multidisciplinary medical journal that aims to publish outstanding human studies that substantially enhance the understanding of human health and disease. It aims to promote translation of basic research into clinical investigation, and of clinical evidence into practice. It encourages papers that cross disciplines.
