New Name Reflects Company’s Focus on Regenerative OphthalmologyTMNew Website Launched at www.ocata.com, new ticker: OCAT

Advanced Cell Technology, Inc., (OTCBB: OCAT) today announced the change of its company name to Ocata Therapeutics, Inc., effective immediately. The change, which has been approved by the Company’s shareholders, reflects the Company’s focus on the development of regenerative cell therapeutics for the treatment of ophthalmic diseases. “Ocata” is a Native American name for “healer,” a term associated with repair and regeneration as opposed to merely slowing the progression of disease, or treatment of symptoms.

Dr. Paul Wotton, President and CEO of Ocata Therapeutics, said: “This is a time of transformation for our company as we continue to advance our technology leadership position in Regenerative Ophthalmology. With that, we determined it was important to select a company name that best reflects our focus going forward. As we prepare to initiate Phase 2 clinical trials for Stargardt’s macular degeneration (SMD) and dry age-related macular degeneration (AMD), we are positioning Ocata to lead the way in developing safe and effective therapies for those suffering from either disease.”

In October, the Company announced results from two Phase 1/2 clinical trials published in The Lancet. The study demonstrated positive first time, mid- to long-term safety results and signs of visual improvement following transplantation of differentiated retinal pigment epithelium cells (RPE) derived from stem cells, for the treatment of both AMD and SMD. There are currently no approved treatments for either disease.

About Age-related Macular Degeneration

Age-related macular degeneration is the leading cause of vision loss in people over the age of 50. Every year in the USA there are 1.8 million patients newly diagnosed with dry AMD which occurs when light-sensitive photoreceptor cells in the macula, located in the center of the retina, slowly break down, causing vision loss as a result. Photoreceptor breakdown is a consequence of loss or damage to the RPE layer. As the disease progresses, patients may have difficulty reading and recognizing faces. There is currently no proven medical therapy for dry AMD and the projected number of people worldwide with age-related macular degeneration in 2020 is 196 million, increasing to 288 million in 2040 underscoring the urgent need for new treatments.

About Stargardt’s Disease

Stargardt’s macular degeneration is a form of juvenile macular degeneration that affects vision in children and young adults between the ages of six and 20, with a prevalence of approximately one in 10,000 people in the United States. It is an orphan disease and loss of vision is an inevitable aspect of SMD, with more than half of the patients experiencing vision loss in the range of 20/200-20/400. Like dry AMD, it occurs as a result of damage to the RPE layer and there are no treatments currently approved to prevent or slow the vision loss associated with SMD.
