Methods for gene transfer in stem cells featured in Cold Spring Harbor Protocols
Vectors derived from retroviruses are useful tools for long-term gene transfer because they allow stable integration of transgenes and propagation into daughter cells. view more (2009-08-06)
Researchers from CIC bioGUNE have found a way to treat ischemic pathologies
A team of researchers from CIC bioGUNE from the Cellular Biology and Stem Cell Unit, alongside a team from Paris' Cardiovascular Research Centre (INSERM U970) have developed a new area of research which looks extremely promising as regards the development of new therapeutic responses to ischemic pathologies and cardiovascular diseases in general. view more (2009-08-05)
Stem cell 'daughters' lead to breast cancer
Walter and Eliza Hall Institute scientists have found that a population of breast cells called luminal progenitor cells are likely to be responsible for breast cancers that develop in women carrying mutations in the gene BRCA1. view more (2009-08-03)
UF scientists program blood stem cells to become vision cells
University of Florida researchers were able to program bone marrow stem cells to repair damaged retinas in mice, suggesting a potential treatment for one of the most common causes of vision loss in older people. view more (2009-07-31)
Reprogramming Human Cells Without Inserting Genes
A research team comprised of faculty at Worcester Polytechnic Institute's (WPI) Life Sciences and Bioengineering Center (LSBC) and investigators at CellThera, a private company also located at the LSBC, has discovered a novel way to turn on stem cell genes in human fibroblasts (skin cells) without the risks associated with inserting extra genes or... view more...

Study shows cancer vaccines led to long-term survival for patients with metastatic melanoma
Hoag Memorial Hospital Presbyterian today announced promising data from a clinical study showing patient-specific cancer vaccines derived from patients' own cancer cells and immune cells were well tolerated and resulted in impressive long-term survival rates in patients with metastatic melanoma whose disease had been minimized by other therapies. view more (2009-07-29)
Male germ cells can be directly converted into other cell types
Researchers have found a way to directly convert spermatogonial stem cells, the precursors of sperm cells, into tissues of the prostate, skin and uterus. view more (2009-07-29)
Duke scientists create airway spheres to study lung diseases
Using both animal and human cells, Duke University Medical Center scientists have demonstrated that a single lung cell can become one of two very different types of airway cells, which could lead to a better understanding of lung diseases. view more (2009-07-29)
Stem cell research: From molecular physiology to therapeutic applications
Stem cell research promises remedies to many devastating diseases that are currently incurable, ranging from diabetes and Parkinson's disease to paralysis. view more (2009-07-29)
How the pathology of Parkinson's disease spreads
Accumulation of the synaptic protein alpha-synuclein, resulting in the formation of aggregates called Lewy bodies in the brain, is a hallmark of Parkinson's and other related neurodegenerative diseases. view more (2009-07-28)
American Chemical Society supports House increase in math, science funding
American Chemical Society (ACS) President Thomas H. Lane, Ph.D., today praised the House of Representatives for supporting a $5 million increase in funding for the Education Department's Math and Science Partnership program, which he called a "critical educational program." view more (2009-07-27)
An 'eye catching' vision discovery
Nearly all species have some ability to detect light. At least three types of cells in the retina allow us to see images or distinguish between night and day. Now, researchers at the Johns Hopkins School of Medicine have discovered in fish yet another type of cell that can sense light and contribute to vision. view more (2009-07-27)
Scientists closer to making implantable bone material, thanks to new research
Scientists are closer to understanding how to grow replacement bones with stem cell technology, thanks to research published today in the journal Nature Materials. view more (2009-07-27)
Stem cells not the only way to fix a broken heart
Researchers appear to have a new way to fix a broken heart. They have devised a method to coax heart muscle cells into reentering the cell cycle, allowing the differentiated adult cells to divide and regenerate healthy heart tissue after a heart attack. view more (2009-07-24)
Stripping leukemia-initiating cells of their 'invisibility cloak'
Two new studies reveal a way to increase the body's appetite for gobbling up the cancer stem cells responsible for acute myeloid leukemia (AML), a form of cancer with a particularly poor survival rate. view more (2009-07-24)
Injection reverses heart-attack damage
Injured heart tissue normally can't regrow, but researchers at Children's Hospital Boston have now laid the groundwork for regenerating heart tissue after a heart attack, in patients with heart failure, or in children with congenital heart defects. view more (2009-07-24)
Reprogrammed mouse fibroblasts can make a whole mouse
In a paper publishing online July 23 in Cell Stem Cell, a Cell Press journal, Dr. Shaorong Gao and colleagues from the National Institute of Biological Sciences in Beijing, China, report an important advance in the characterization of reprogrammed induced pluripotent stem cells, or iPSCs. view more (2009-07-24)
July 23, 2009 Circulating osteogenic precursor (COP) cells form bone in vivo. Bone from Blood: Circulating Cells Form Bone Outside the Normal Skeleton, Penn Study Finds
The accepted dogma has been that bone-forming cells, derived from the body's connective tissue, are the only cells able to form the skeleton. view more (2009-07-24)
Study provides documentation that tumor 'stem-like cells' exist in benign tumors
Cancer stem-like cells have been implicated in the genesis of a variety of malignant cancers. Research scientists at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute have isolated stem-like cells in benign (pituitary) tumors and used these "mother" cells to generate new tumors in laboratory mice. view more (2009-07-23)
Skin-like Tissue Developed from Human Embryonic Stem Cells
Dental and tissue engineering researchers at Tufts University School of Dental Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts have harnessed the pluripotency of human embryonic stem cells (hESC) to generate complex, multilayer tissues that mimic human skin and the oral mucosa (the moist tissue that lines the inside of the... view more...
