ALAMEDA, Calif. -- Advanced Cell Technology (ACTC), Inc. (OTCBB:ACTC), applying proprietary human embryonic stem (ES) cell technology to the emerging field of regenerative medicine, announced today that William Caldwell IV, Chairman and Chief Executive Officer, has been invited to present an overview of the Company's proprietary stem cell science and therapeutic programs at the upcoming 4th Annual Commercialization of Tissue Engineering and Cell Therapy, to be held December 14 and 15, 2006, in London.

The conference is designed to bring together research, academic and business leaders who are driving progress in cell-based sciences and industry. Attendees and speakers will address fundamental challenges and opportunities of producing cell-based therapies, with a focus on the strategic path to bring products to market.

In his keynote address, Mr. Caldwell will discuss ACTC's unique technologies as well as its overall strategies for developing medically valuable therapies for a number of market segments in medicine and health care. ACTC has pioneered a range of innovations relating to human embryonic stem cells, and is committed to taking a leadership role in the development of stem cell based therapies to cure or treat a range of serious diseases, injuries and degenerative medical conditions.

Mr. Caldwell's presentation is scheduled for December 15, 2006, at 9:10 am GMT. The conference will be held at the Grange Holborn Hotel in London.

"I believe that we are at a pivotal point in our industry's evolution, where research has begun to show the vast potential of stem cell-based therapies to offer important advances in medical care," said Mr. Caldwell. "At ACTC, we are already employing innovative solutions in both basic science as well as product applications, and I look forward to sharing our ideas with my colleagues in the extended international community of scientists and business leaders."

ACTC's mission is to develop stem cell based treatments and therapies for a broad range of disease and injuries. Embryonic stem cells promise to provide a well-characterized and reproducible source of replacement tissue for human clinical studies. One of ACTC's lead development programs applies human embryonic stem cell (hESC)-derived retinal pigment epithelium (RPE) for the treatment of retinal degenerative diseases such as macular degeneration and retinitis pigmentosa. Another development program focuses on the use of hESC-derived hemangioblasts for vascular restoration of organs and limbs.
