Johns Hopkins scientists map brain area that may aid hunt for human brain stem cells
A study led by a Johns Hopkins neurosurgeon has provided the first comprehensive map of a part of the adult human brain containing astrocytes, cells known to produce growth factors critical to the regeneration of damaged neural tissue and that potentially serve as brain stem cells.   view more (2006-02-17)

Gene silencing directs muscle-derived stem cells to become bone-forming cells
Using a relatively new technology called RNA interference to turn off genes that regulate cell differentiation, University of Pittsburgh researchers have demonstrated they can increase the propensity of muscle-derived stem cells (MDSCs) to become bone-forming cells.   view more (2006-06-02)

Identification of dopamine 'mother cells' could lead to future Parkinson's treatments
'Mother cells' which produce the neurons affected by Parkinson's disease have been identified by scientists, according to new research published in the journal Glia.   view more (2008-04-08)

Stem Cells from Hair Follicles May Help
For a rich source of stem cells to be engineered into new blood vessels or skin tissue, clinicians may one day look no further than the hair on their patients' heads, according to new research published earlier this month by University at Buffalo engineers.   view more (2008-03-31)

Cancer stem cells linked to radiation resistance
Certain types of brain cancer cells, called cancer stem cells, help brain tumors to buffer themselves against radiation treatment by activating a "repair switch" that enables them to continue to grow unchecked.   view more (2006-10-19)

Protein maintains cross talk between cells that control hair growth
Genes, it turns out, are only as active as the signals that turn them on and off. Now scientists from Rockefeller University and the Howard Hughes Institute have identified the signaling molecule that ratchets up and clamps down the activity of key genes in dermal papilla, a type of skin cell whose... view more (2008-02-15)

Experts discuss use of human stem cells in ape and monkey brains
An expert panel of stem cell scientists, primatologists, philosophers and lawyers has concluded that experiments implanting, or grafting, human stem cells into non-human primate brains could unintentionally shift the moral ground between humans and other primates.   view more (2005-07-15)

Blood stem cells fight invaders, study finds
No other stem cell is more thoroughly understood than the blood, or hematopoietic, stem cell.   view more (2007-11-30)

Dual functions of gene revealed, for better and for worse
Researchers at WEHI have pinpointed the function of a potent cancer gene. The gene, known as "ERG", has long been associated with a range of human malignancies, including leukemia and sarcoma. American scientists showed in 2005 that ERG is mutated in more than half of all prostate... view more (2008-05-27)

New treatment for glaucoma shows promise in laboratory, say Iowa State researchers
Iowa State University researchers have developed a new technique that successfully treated rats for blindness caused by glaucoma.   view more (2007-08-02)

Discovery of good -- and bad -- liver stem cells raises possibility of new treatment
Many scientists believe up to 40 percent of liver cancer is caused by stem cells gone wild - master cells in the organ that have lost all growth control. But, despite years spent looking, no one has ever found these liver "cancer stem cells" - or even normal stem cells in the organ. Until... view more (2008-02-11)

Silenced gene in worm shows role in regeneration
Researchers at the University of Utah have discovered that when a gene called smedwi-2 is silenced in the adult stem cells of planarians, the quarter-inch long worm is unable to carry out a biological process that has mystified scientists for centuries: regeneration.   view more (2005-11-28)

NC State Is First University in Nation to Offer Canine Bone Marrow Transplants
Dogs suffering from lymphoma will be able to receive the same type of medical treatment as their human counterparts, as North Carolina State University becomes the first university in the nation to offer canine bone marrow transplants in a clinical setting.   view more (2008-09-04)

The difference between fish and humans: scientists answer century-old developmental question
Embryologists at UCL (University College London) have helped solve an evolutionary riddle that has been puzzling scientists for over a century.   view more (2007-10-11)

Lost in the labyrinth
Blood cells have limited lifespans, which means that they must be continually replaced by calling up reserves, and turning these into the blood cell types needed by the body.   view more (2006-09-05)

New cell type identified in cancer development
Scientists have discovered a new type of cell that appears to play a role in the development of cancer - a highly volatile, precancerous stem cell that can either remain benign or become malignant, depending upon environmental cues.   view more (2007-03-14)

AN EYE FOR AN EYE: Using stem cells to treat damaged eyes and a rare skin disorder
Doctors and scientists in Italy have shown how stem cells can be used to treat damaged eyes and, in combination with gene therapy, a rare and debilitating skin disease.   view more (2007-10-23)

Computation to unravel how genes are regulated and shed light on how cells become different
A closer alliance between computational and experimental researchers is needed to make progress towards one of biology's most challenging goals, understanding how epigenetic marks contribute to regulation of gene expression.   view more (2008-04-11)

Scientists ask whether microscaffolding can help stem cells rebuild brain after stroke damage
Inserting tiny scaffolding into the brain could dramatically reduce damage caused by strokes the UK National Stem Cell Network Annual Science Meeting will hear today (10 April).   view more (2008-04-10)

Human muscle-derived stem cells effective in animal models of incontinence
Human muscle-derived cells, pluripotent stem cells found in muscle, have been used to cure stress urinary incontinence in animal models, a finding which signals that these cells are prime candidates to treat the condition in adults.   view more (2005-09-01)

Transplanted brain cells hold promise for Parkinson's disease
Transplanted neural stem cells hold promise for reducing the destruction of dopaminergic cells that occurs in Parkinson's disease and for replacing cells lost to the disease, scientists say.   view more (2006-12-05)

Aggressive stem cells might improve transplant outcome
Investigators at St. Jude Children's Research Hospital have demonstrated in mice a way that might reduce the time it takes for a bone marrow transplant to rebuild a child's immune system, and so reduce the risk of potentially fatal virus infections that can occur during this time.   view more (2006-12-08)

Injecting stem cells from a woman's own muscle may effectively treat urinary incontinence
In the first clinical study of its kind in North America, women with stress urinary incontinence (SUI) were treated using muscle-derived stem cell injections to strengthen deficient sphincter muscles responsible for the condition.   view more (2006-05-22)

Adult stem cells activated in mammalian brain
Adult stem cells originate in a different part of the brain than is commonly believed, and with proper stimulation they can produce new brain cells to replace those lost to disease or injury, a study by UC Irvine scientists has shown.   view more (2008-07-25)

A stem cell type supposed to be crucial for angiogenesis and cancer growth does not exist?
Angiogenesis, the growth of new blood vessels, is a central process in diverse physiological and pathological situations such as healing of wounds and traumas, cardiovascular disorders, inflammatory conditions such as rheumatoid arthritis, and in cancer growth.   view more (2008-04-23)
