WOONSOCKET, R.I., March 19 /PRNewswire-FirstCall/ --MultiCell Technologies, Inc. (OTC Bulletin Board: MCET) announced today that it has entered into a cooperative research and development agreement with Maxim Biotech, Inc. to develop products for the study of liver stem cells and liver cancer.
Tumor tissues are composed of a mixture of cells with some tumor cells exhibiting stem cell-like properties (cancer stem cells). Cancer stem cells are thought to play a role in a tumor's resistance to therapy. While significant progress has been made in developing cancer therapies that result in cytoreduction and thus tumor regression, the control of cancer over a longer interval and especially of metastatic disease, remains a key goal. Cancer stem cells are believed to be responsible for cancer relapse by being less sensitive to conventional therapies. Cancer stem cells may offer a unique opportunity to identify and develop a new generation of more effective anticancer agents (both small molecule therapeutics and biotherapies).
MultiCell owns exclusive rights to two issued U.S. patents (6,872,389 and 6,129,911), one U.S. patent application (U.S. 2006/0019387A1), and several corresponding issued and pending foreign patents and patent applications related to the isolation and differentiation of liver stem cells. The role of liver stem cells in the carcinogenic process has recently led to a new hypothesis that hepatocellular carcinoma arises by maturation arrest of liver stem cells.
Primary liver cancer begins in the cells of the liver itself. According to the National Cancer Institute (NCI), in 2008 there were approximately 21,400 new cases of primary liver cancer and intrahepatic bile duct cancer in the United States, and approximately 18,400 of those cases resulted in death. Hepatocellular carcinoma, resulting from Hepatitis B and Hepatitis C infection, is the most common cancer in some parts of the world, wit
