Medistem and Collaborators Publish Arthritis Paper

SCOTTSDALE, AZ--(Marketwire - February 22, 2008) - Medistem Laboratories, Inc. (OTCBB: MDSM) (Frankfurt: S2U) announced today the publication of a paper entitled "Antigen-specific therapy of rheumatoid arthritis" in the February issue of the peer-reviewed journal Expert Opinion on Biological Therapies. The article, which was written by scientists at Medistem, the University of Western Ontario, and the University of Toronto, describes methods of selectively inhibiting pathological immune responses in arthritis patients. An abstract of the article may be found at

"The importance of immunology in any stem cell endeavor can not be underestimated. By working with internationally renowned scientists such as Dr. Wei-Ping Min, Medistem seeks to not only regenerate injured tissue in diseases such as rheumatoid arthritis, but also to stop the original cause of the injury; that cause being a misguided immune response against proteins in the joints," said Thomas Ichim, the first author of the paper and Medistem's Chief of Scientific Development.

Medistem's lead product, a menstrual blood derived stem cell termed the endometrial regenerative cell (ERC), appears to possess the ability to modulate pathological immune responses, and is currently undergoing investigative tests.

"Currently, the majority of treatment approaches for pathological immune responses involve non-specific immune suppression. This causes potential side effects such as increased risks of viral and bacterial infections," said Dr. Wei-Ping Min, the senior author of the paper. "Understanding and manipulating the molecular mechanisms that activate self-reactive responses provides a potential means of logically addressing the problem of autoimmunity."
