Major Paper Shows How Melligen Cell Line Derived from Human Liver Cells Can Reverse Diabetes

New paper in the journal Molecular Therapy – Methods & Clinical Development describes how Melligen cell lines coupled with a live cell encapsulation technology such as Cell-in-a-Box® can reverse Type I Diabetes per a team at the University of Technology Sydney and the University of Sydney in Australia

 

Silver Springs, MD -- (SBWIRE) -- 04/14/2015 -- A recently published paper in the scientific journal Molecular Therapy – Methods & Clinical Development puts the spotlight on novel research that has been done by a team at the University of Technology Sydney (UTS) and the University of Sydney in Australia. The research team observed that a cell line called "Melligen" cells that was derived from human liver cells show real promise as a potential treatment for Type 1 diabetes because these cell are capable of regulating blood glucose (sugar) levels by producing insulin on demand. This observation, noted the authors, illustrates that Melligen cells can reverse the diabetic condition.

Using technology licensed by PharmaCyte Biotech, Inc., a clinical stage biotechnology company focused on developing targeted treatments for cancer and diabetes (using its signature live-cell encapsulation technology, Cell-in-a-Box®), Prof. Ann Simpson (a member of PharmaCyte Biotech's international Diabetes Consortium) and her colleagues at the University of Technology Sydney and the University of Sydney in Australia describe the development of the Melligen cell line and note that it was developed from human liver cells in their latest paper titled "Reversal of diabetes following transplantation of an insulin-secreting human liver cell line: Melligen cells" in the journal Molecular Therapy – Methods & Clinical Development. This journal is part of the prestigious Nature Publishing Group and is the official journal of the American Society for Gene and Cell Therapy.

Numerous tests were done during the various stages of the development process and studies were carried out to show that Melligen cells secreted insulin in response to physiological concentrations of glucose (blood sugar). Furthermore, when Melligen cells were transplanted into diabetic mice whose immune systems were essentially not functioning, the blood glucose levels of the mice became normal.

Most importantly, however, the authors of the article note that, for the Melligen cells to be effective in treating Type 1 diabetes in humans where the insulin-producing cells of the pancreas have been destroyed, it will be necessary to protect the Melligen cells from rejection by the body's immune system after they have been introduced into the body. The article points out that one way to protect the Melligen cells would be to encapsulate the cells in protective "cocoons" prior to being placed into a diabetic patient. If this is done, the authors believe that encapsulated Melligen cells may offer a cure for Type 1 diabetes.

Prof. Simpson commented, "Type 1 diabetes mellitus is a serious disorder that significantly reduces patients' quality of life and costs governments many millions of dollars in patient care. It is hoped that the Melligen cells, which have been shown to reverse diabetes in rodents with a normal response to glucose, once encapsulated in the Cell-in-a-Box® capsules, will be an easily accessible treatment for patients."

Kenneth L. Waggoner, CEO of PharmaCyte Biotech, added, "PharmaCyte Biotech's live cell encapsulation technology, Cell-in-a-Box®, appears to be the ideal encapsulation technology for this purpose. In fact, Melligen cells have already been successfully encapsulated using the Cell-in-a-Box® process and experiments are already underway to ensure that encapsulation does not detract from the beneficial properties of the Melligen cells in any way.

About PharmaCyte Biotech
PharmaCyte Biotech is a clinical stage biotechnology company focused on developing and preparing to commercialize treatments for cancer and diabetes based upon a proprietary cellulose-based live cell encapsulation technology known as Cell-in-a-Box®. This unique and patented technology will be used as a platform upon which treatments for several types of cancer, including advanced, inoperable pancreatic cancer, and diabetes are being built. PharmaCyte Biotech's treatment for pancreatic cancer involves low doses of the well-known anticancer prodrug ifosfamide, together with encapsulated live cells, which convert ifosfamide into its active or "cancer-killing" form. These capsules are placed as close to the cancerous tumor as possible to enable the delivery of the highest levels of the cancer-killing drug at the source of the cancer. This "targeted chemotherapy" has proven remarkably effective and safe to use in past clinical trials. In addition, PharmaCyte Biotech is working towards improving the quality of life for patients with advanced pancreatic cancer and on treatments for other types of solid cancerous tumors.

PharmaCyte Biotech is also developing treatments for cancer based upon chemical constituents of the Cannabis plant, known as cannabinoids. In doing so, PharmaCyte Biotech is examining ways to exploit the benefits of Cell-in-a-Box® technology in optimizing the anticancer effectiveness of cannabinoids, while minimizing or outright eliminating the debilitating side effects usually associated with cancer treatments. This provides PharmaCyte Biotech the rare opportunity to develop "green" approaches to fighting deadly diseases, such as cancer of the pancreas, brain and breast, which affect hundreds of thousands of individuals worldwide every year.
