Dopamine drug leads to new neurons and recovery of function in rat model of Parkinson's
In preliminary results, researchers have shown that a drug which mimics the effects of the nerve-signaling chemical dopamine causes new neurons to develop in the part of the brain where cells are lost in Parkinson's disease (PD). view more (2006-07-05)
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)
Gradient guides nerve growth down spinal cord
The same family of chemical signals that attracts developing sensory nerves up the spinal cord toward the brain serves to repel motor nerves, sending them in the opposite direction, down the cord and away from the brain. view more (2005-08-15)
Adult human neural stem cell therapy successful in treating spinal cord injury
Researchers at the UC Irvine Reeve-Irvine Research Center have used adult human neural stem cells to successfully regenerate damaged spinal cord tissue and improve mobility in mice. view more (2005-09-20)
Knowledge of dendritic cells branches out
Dendritic cells (or "DC" ) are specialised white blood cells that patrol the body, searching for infections. view more (2006-05-09)
Study establishes safety of spinal cord stem cell transplantation
Transplanting human embryonic stem cells does not cause harm and can be used as a therapeutic strategy for the treatment of acute spinal cord injury. view more (2006-07-20)
Mayo Clinic research shows promise for myeloma patients
Mayo Clinic Cancer Center investigators report that combination therapy with lenalidomide (RevlimidTM) and dexamethasone (combination is called Rev/Dex) looks like a breakthrough treatment for multiple myeloma. view more (2005-09-02)
Tapping into spinal cures
Stem cells which give rise to vertebrae, muscle and the spinal cord have been identified for the first time by Dr. Valerie Wilson (University of Edinburgh). "These axial stem cells could be used in the future to help replace damaged tissues after back injuries", says Dr. Wilson who will be presenting her work at the Society for... view more...

UCLA researchers discover new disorder that causes chronic diarrhea in children
UCLA researchers have unraveled a mysterious condition that causes congenital diarrhea and intestinal failure in children. view more (2006-07-20)
Human Reproductive And Therapeutic Cloning
For Immediate Release Monday, 22 September 2003 International Scientific Body Calls For Ban On Human Reproductive Cloning More than 60 science academies from every continent in the world have called on the United Nations to adopt a ban on human reproductive cloning. The statement was issued by the InterAcademy Panel on International Issues (IAP),... view more... (2003-09-22)
Genetics of muscular dystophy
Various forms of human muscular dystrophy result from mutations in genes encoding proteins of the nuclear envelope. A new paper in the February 15th issue of G&D reveals how. view more (2006-02-15)
Protein-coated dental implants could improve bone regeneration
Titanium dental implants coated with proteins that induce bone formation may be a key advancement in treating tooth loss due to gum disease, researchers say. view more (2006-07-18)
First for stem cell researcher
In an Australian-first, a UNSW researcher based at the Diabetes Transplant Unit at the Prince of Wales Hospital has produced a human embryonic stem cell (hESC) line without the use of any animal products. view more (2006-01-23)
Natural protein stops deadly human brain cancer in mice
Scientists from Johns Hopkins and from the University of Milan have effectively proven that they can inhibit lethal human brain cancers in mice using a protein that selectively induces positive changes in the activity of cells that behave like cancer stem cells. view more (2006-12-08)
Cancer stem cells spur glioma Angiogenesis, could hold key to brain tumor therapy
Stem cell-like glioma cancer cells that share many characteristics with normal stem cells propel the lethal growth of brain cancers by promoting tumor blood vessel formation, and may hold the key to treating these deadly cancers. view more (2006-08-15)
Factor stimulates cartilage growth from stem cells
A novel growth factor significantly improves the ability of specialized stem cells derived from human fat to be transformed into cartilage cells, according to Duke University Medical Center and Pratt School of Engineering researchers. view more (2006-04-05)
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)
Researchers Discover New Factor in Nerve Regeneration
Researchers in Oxford University's Department of Human Anatomy have identified a factor involved in the regeneration of neurons in the central nervous system. The discovery and use of this factor could provide the basis for a reparative treatment for both brain and spinal cord injuries. Unlike lower vertebrates, mammals have lost the ability to... view more... (2003-04-07)
Bone marrow may restore cells lost in vision diseases
University of Florida scientists conducting experiments with mice have found evidence that the body naturally replenishes small amounts of cells in the eye essential for healthy vision. view more (2006-06-09)
Powerful technique for multiplying adult stem cells may aid therapies
Adult stem cells may be free of the ethical concerns that hamper embryonic stem cell research, but they still pose formidable scientific challenges. Chief among these is the doggedness with which adult stem cells differentiate into mature tissue the moment they're isolated from the body. view more (2006-01-23)
