MicroIslet and Progenitor Cell Therapy Enter Into Agreement for the Manufacturing of MicroIslet-P, an Encapsulated Islet Cell Product for the Treatment of Type 1 Diabetes


SAN DIEGO and HACKENSACK, N.J., Sept. 17, 2007 (PRIME NEWSWIRE) -- MicroIslet, Inc. (OTCBB:MIIS), a development-stage biotechnology company with patented and proprietary technologies focused on transplantation therapy for people with insulin-dependent diabetes, and Progenitor Cell Therapy, LLC (PCT), a leading cell therapy services company, announced today that they have signed an agreement for the manufacturing of MicroIslet's premier product, MicroIslet-P(tm).

MicroIslet-P(tm) consists of microencapsulated porcine islets for implantation into the abdominal cavity using a minimally invasive procedure. Microencapsulation involves surrounding islet cells with formulations of a highly biocompatible, ultra-pure biopolymer, called alginate, or other similar biocompatible polymers. The alginate coating allows insulin, glucose, oxygen and other nutrients to diffuse freely, while blocking antibodies and reducing the patient's immune response to the implanted islet cells. It is hoped that MicroIslet-P(tm) will provide physiologic and self-regulating blood glucose control, thus reducing the need for insulin injections or infusions and constant blood glucose monitoring. The long-term complications associated with type 1 diabetes, such as peripheral neuropathies, heart and kidney disease, and skin disorders, may be mitigated by the tighter blood glucose control that would result from such a product.

MicroIslet-P(tm) will be manufactured at PCT's California facility under strict cGMP (current Good Manufacturing Practices) and will be used in MicroIslet's ongoing preclinical studies and planned clinical programs.

"MicroIslet has refocused its efforts to accelerate the clinical testing of the Company's xenograft MicroIslet-P(tm) product. This plan required us to secure a cGMP manufacturing partner to produce MicroIslet-P(tm) for human trials. This arrangement with PCT is a major step forward toward execution of our plan. PCT has state-of-the-art facilities and some of the most qualified cell therapy specialists I have encountered in my 25-year career in biological manufacturing. We are quite pleased to be working with PCT," said Mike Andrews, MicroIslet's chief executive officer.

"Progenitor Cell Therapy's management team has over 100 years combined experience in cell therapy, built 5 cGMP facilities, and participated in over 50 regulatory filings in the US and Europe. The company has, to date, served over 100 clients, manufactured over 17,000 cell therapy products, approximately 5,000 of which have already been used for patient treatment, and performed over 30,000 cell therapy procedures involving over 20 different types of cell-based products. We are pleased to be leveraging this experience for MicroIslet," said Dr. Robert A. Preti, president and chief scientific officer of PCT.
