How Embryonic Stem Cells Maintain Their Identity
Two studies in the April 2006 Cell report new details of the “genetic program” that affords embryonic stem cells the flexibility to give rise to any cell type in the body.
Cytori Therapeutics Demonstrates Adipose Stem and Regenerative Cells Reduce Incidence of Arrhythmia after Heart Attacks in Preclinical Study
Cytori Therapeutics, Inc. announced preclinical data demonstrating that adipose stem and regenerative cell-based therapy following a heart attack in pigs is not associated with an increased risk of irregular heart rhythms.
Thailand to Begin Stemcell Heart Study
Thai scientists are set to begin the country’s first official study into the effects of stem cell technology in curing heart disease.
Cell Discovery on Breast Cancer
Australian researchers have discovered how pre-cancerous cells evade early detection and develop unhindered into breast cancer tumours — a finding that could lead to a new treatment for the disease.
Primitive Adult Stem Cells Found in Peripheral Blood
Moraga Biotechnology Corporation, an adult stem cell company based in Los Angeles, California, announces the discovery of its proprietary Blastomere-Like Stem Cells (BLSCs) circulating in the peripheral blood of mammals.
Stem Cell Study for Patients with Heart Attack Damage Seeks to Regenerate Heart Muscle

ABSTRACTS, REVIEWS & SPECIAL REPORTS
Control of Developmental Regulators by Polycomb in Human Embryonic Stem Cells
The results indicate that PRC2 occupies a special set of developmental genes in ES cells that must be repressed to maintain pluripotency and that are poised for activation during ES cell differentiation.
A Bivalent Chromatin Structure Marks Key Developmental Genes in Embryonic Stem Cells
The results highlight the importance of DNA sequence in defining the initial epigenetic landscape and suggest a novel chromatin-based mechanism for maintaining pluripotency.
