MARLBOROUGH, Mass.--(BUSINESS WIRE)--

Advanced Cell Technology, Inc. (ACT; OTCBB: ACTC), a leader in the field of regenerative medicine, today announced treatment of the fourth patient, the first in the second patient cohort, in its U.S. clinical trial for Stargardts Macular Dystrophy (SMD). The surgery was performed on Wednesday, July 11 at Wills Eye Institute in Philadelphia, by a surgical team lead by Carl D. Regillo, MD, FACS, director of the Wills Eye Clinical Retina Research Unit, attending surgeon in the Wills Eye Retina Service at the Wills Eye Institute, and professor of ophthalmology at Thomas Jefferson University. In keeping with trial protocol, the patient was injected with 100,000 human embryonic stem cell-derived retinal pigment epithelial (RPE) cells, as compared with the 50,000 cell dose used in the three patients of the first cohort. The outpatient transplantation surgery was performed successfully and the patient is recovering uneventfully.

It is very gratifying to have second cohort, higher-dosage patient treatment underway in our U.S. clinical trial for SMD, commented Gary Rabin, chairman and CEO of ACT. We are also pleased to be working with Dr. Regillo and his team at Wills Eye Institute, a truly first-class institution that is ranked as one of the best ophthalmology hospitals in the country byU.S. News & World Report.

Initiated in July of last year, the Phase I/II trial is designed to determine the safety and tolerability of hESC-derived RPE cells following sub-retinal transplantation in patients with SMD at 12 months, the studys primary endpoint. It will involve a total of 12 patients, with cohorts of three patients each in an ascending dosage format. As part of its RPE clinical program, the company is concurrently conducting a clinical trial for dry age-related macular degeneration and second trial for SMD in the United Kingdom.

Doubling the cell dosage marks an important milestone in our clinical programs, said Robert Lanza, MD, ACTs chief scientific officer. We look forward to continued progress and safety findings in the coming months, in both our U.S. and European trials.

Further information about patient eligibility for ACTs SMD study and the concurrent studies in the U.S. and Europe (for dry age-related macular degeneration and SMD, respectively) are available at http://www.clinicaltrials.gov, with the following Identifiers: NCT01345006 (U.S. SMD), NCT01344993 (dry AMD), and NCT01469832 (E.U. SMD).

About Stargardts Disease

Stargardts disease or Stargardts Macular Dystrophy is a genetic disease that causes progressive vision loss, usually starting in children between 10 to 20 years of age. Eventually, blindness results from photoreceptor loss associated with degeneration in the pigmented layer of the retina, called the retinal pigment epithelium, which is the site of damage that the company believes the hESC-derived RPE may be able to target for repair after administration.

ACT Announces First Stargardt Patient Treated With Higher Dosage of Embryonic Stem Cell-Derived Retinal Pigment ...

ScienceDaily (July 9, 2012) The ability to control whether certain stem cells ultimately become bone cells holds great promise for regenerative medicine and potential therapies aimed at treating metabolic bone diseases.

Now, UCLA School of Dentistry professor and leading cancer scientist Dr. Cun-Yu Wang and his research team have made a significant breakthrough in that direction. The scientists have discovered two key epigenetic regulating genes that govern the cell-fate determination of human bone marrow stem cells.

Wang's new research is featured on the cover of the July 6 issue of Cell Stem Cell, the affiliated journal of the International Society for Stem Cell Research.

The groundbreaking study grew out of Wang's desire to better understand the epigenetic regulation of stem cell differentiation, in which the structure of genes is modified while the sequence of the DNA is not. He and his team found that KDM4B and KDM6B, two gene-activating enzymes, can promote stem cells' differentiation into bone cells by removing methyl markers from histone proteins. This process occurs through the activation of certain genes favoring a commitment to one lineage and the concurrent deactivation of genes favoring other lineages.

The findings imply that chemical manipulation of these gene-activating enzymes may allow stem cells to differentiate specifically into bone cells, while inhibiting their differentiation into fat cells. The group's research could pave the way toward identifying potential therapeutic targets for stem cell-mediated regenerative medicine, as well as the treatment of bone disorders like osteoporosis, the most common type of metabolic bone disease.

"Through our recent discoveries on the lineage decisions of human bone marrow stem cells, we may be more effective in utilizing these stem cells for regenerative medicine for bone diseases such as osteoporosis, as well as for bone reconstruction," Wang said. "However, while we know certain genes must be turned on in order for the cells to become bone-forming cells, as opposed to fat cells, we have only a few clues as to how those genes are switched on."

The research group, through its study of aging mice, found that the two enzymes KDM4B and KDM6B could specifically activate genes that promote stem cell differentiation toward bone, while blocking the route toward fat.

"Interestingly, in our aged mice, as well as osteoporotic mice, we observed a higher amount of silencing histone methyl groups which were normally removed by the enzymes KDM4B and KDM6B in young and healthier mice," Wang said. "And since these enzymes can be easily modified chemically, they may become potential therapeutic targets in tissue regeneration and treatment for osteoporosis."

"The discovery that Dr. Wang and his team have made has considerable implications for craniofacial bone regeneration and treatment for osteoporosis," said Dr. No-Hee Park, dean of the UCLA School of Dentistry. "As a large portion of our population reaches an age where osteoporosis and gum disease could be major health problems, advancements in aging-related treatment are very valuable."

Professor Wang holds the No-Hee Park Endowed Chair in Dentistry at the UCLA School of Dentistry, where he is also chair of the division of oral biology and medicine and the associate dean for graduate studies.

Discovery of epigenetic links in cell-fate decisions of adult stem cells paves way for new osteoporosis treatments

MARLBOROUGH, Mass.--(BUSINESS WIRE)--

Advanced Cell Technology, Inc. (ACT; OTCBB: ACTC), a leader in the field of regenerative medicine, announced today that the Data and Safety Monitoring Board (DSMB), an independent group of medical experts closely monitoring the companys three ongoing clinical trials, has authorized the company to move forward with enrollment and treatment of additional patients in its clinical trial for dry age-related macular degeneration (dry AMD). ACT will proceed with patient screening and enrollment for the second cohort, who, in keeping with trial protocol, will be injected with 100,000 retinal pigment epithelial (RPE) cells derived from human embryonic stem cells (hESCs), as compared with the 50,000-cell dose used in the first cohort.

DSMB authorization to move to the higher dosage of cells in our clinical trial for dry AMD represents a significant milestone for our clinical programs, commented Gary Rabin, chairman and CEO of ACT. Our RPE program is now advancing rapidly, as we are now screening at multiple ophthalmological centers for the fourth surgery in both our dry AMD trial and our U.S. SMD trial, with our E.U. SMD trial, which was initiated much later, not far behind.

The trial is a prospective, open-label study, designed to determine the safety and tolerability of hESC-derived RPE cells following sub-retinal transplantation into patients with dry AMD at 12 months, the studys primary endpoint. The three procedures comprising the first cohort of patients were all conducted at University of California at Los Angeles (UCLA), by Steven Schwartz, M.D., Ahmanson Professor of Ophthalmology at the David Geffen School of Medicine at UCLA and retina division chief at UCLA's Jules Stein Eye Institute. It was announced in May that Mass Eye and Ear is an additional site for the trial.

Mr. Rabin added, Dry AMD represents one of the largest unmet ophthalmological needs in the world, with a potential market of $25 billion in the U.S. and Europe, alone, and this DSMB approval is a big step toward being able to potentially address that massive medical need.

ACT is conducting a total of three clinical trials in the U.S. and Europe using hESC-derived RPE cells to treat forms of macular degeneration. Each trial will enroll a total of 12 patients, with cohorts of three patients each in an ascending dosage format. Treatment of the final patient of the first cohort in the companys dry AMD trial was announced on April 20. On June 29, the second SMD patient enrolled in the Companys E.U. clinical trial was treated at Moorfields Eye Hospital in London, U.K., and on April 24 the company announced DSMB approval to treat the second patient cohort in its U.S. SMD trial.

Further information about patient eligibility for ACTs dry AMD study and the companys concurrent SMD studies in the U.S. and E.U. is available at http://www.clinicaltrials.gov, with the following Identifiers: NCT01344993 (dry AMD), NCT01345006 (U.S. SMD), and NCT01469832 (E.U. SMD).

ACT Secures Approval to Proceed with Increased RPE Dosage for Patients in Clinical Trial for Dry AMD

Harvard Bioscience's "InBreath" Bioreactors Used in World's First Successful Regenerated Laryngotracheal Transplants

First Two Transplants Performed in Government-Approved Clinical Trial in Russia

HOLLISTON, Mass., June 26, 2012 (GLOBE NEWSWIRE) -- Harvard Bioscience, Inc. (HBIO), a global developer, manufacturer, and marketer of a broad range of tools to advance life science research and regenerative medicine, announces that its "InBreath" bioreactors were used for the world's first and second successful laryngotracheal implants, using synthetic laryngotracheal scaffolds seeded with cells taken from the patients' bone marrow. The surgeries took place at Krasnodar Regional Hospital in Krasnodar, Russia on June 19th and June 21st. The recipients of the implants, Julia T. and Aleksander Z., are recovering well. The implants in the procedures were grown in bioreactors developed by the regenerative medicine device business of Harvard Bioscience.

The transplants, which required more than a half-year of preparation, were performed on the first two patients enrolled in an ongoing clinical trial at Krasnodar Regional Hospital. The Russian Ministry of Health has approved a clinical protocol for an unlimited number of patients in this trial, all of which will involve trachea procedures.

Each bioreactor was specifically adapted by Harvard Bioscience to the clinical requirements for each patient. Each bioreactor was loaded with a synthetic scaffold in the shape of the patient's original organ. The scaffolds were then seeded with the patient's own stem cells. Over the course of about two days, the bioreactor promoted proper cell seeding and development. Because the patients' own stem cells were used, their bodies have accepted the transplants without the use of immunosuppressive drugs.

A photo accompanying this release is available at http://www.globenewswire.com/newsroom/prs/?pkgid=13437

The procedures are the result of a global collaboration involving organizations in the US, Sweden, Russia, Germany, and Italy:

-- The bioreactors were developed, manufactured and prepared by teams at Hugo Sachs Elektronik, a German subsidiary of Harvard Bioscience and at Harvard Bioscience, based in Massachusetts, U.S.A.

-- The scaffolds were created by US-based Nanofiber Solutions.

-- The principal transplant surgeon and main coordinator for both procedures was Dr. Paolo Macchiarini, Professor of Regenerative Surgery at Karolinska Institute in Stockholm.
