A clone in the biological sense, therefore, is a multi-cellular organism that is genetically identical to another living organism. Sometimes this can refer to "natural" clones made when an organism reproduces asexually, but in common parlance the clone is an identical copy by some conscious design. The word was coined by the British geneticist J. B. S. Haldane in 1963, and is derived from the Greek word for "twig", klon.   Stem Cell Research News From Medical News Today Treating Brain Injuries With Stem Cell Transplants - Promising Results The February edition of Neurosurgery reports that animal experiments in brain-injured rats have shown that stem cells injected via the carotid artery travel directly to the brain, greatly enhancing functional recovery... Hepatitis Research May Benefit From Stem Cells Hepatitis C is a viral disease that leads to inflammation and organ failure. However, researchers are puzzled as to why some individuals are very susceptible to the disease, while others are not. Researchers believe they could find out how genetic variations produce these different responses by investigating liver cells from different individuals in the lab... Stem Cells Could Drive Hepatitis Research Forward Hepatitis C, an infectious disease that can cause inflammation and organ failure, has different effects on different people. But no one is sure why some people are very susceptible to the infection, while others are resistant. Scientists believe that if they could study liver cells from different people in the lab, they could determine how genetic differences produce these varying responses... Scientists Transform Skin Cells Direct To Brain Cells, Bypassing Stem Cell Stage Bypassing the stem cell stage, researchers at the Stanford University School of Medicine in California converted mouse skin cells directly into neural precursor cells, the cells that go on to form the three main types of cell in the brain and nervous system. They write about their findings in the 30 January early online issue of the Proceedings of the National Academy of Sciences... Stanford Scientists Turn Skin Cells Into Neural Precusors, Bypassing Stem-Cell Stage Mouse skin cells can be converted directly into cells that become the three main parts of the nervous system, according to researchers at the Stanford University School of Medicine. The finding is an extension of a previous study by the same group showing that mouse and human skin cells can be directly converted into functional neurons... A First For Ontario: Cardiac Stem Cell Transplant Performed At The Peter Munk Cardiac Centre Heart failure is a leading cause of death in Canada... Breast Cancer Survival - Why Avastin And Sutent Don't Help Avastin and Sutent, two cancer drugs, do not lead to longer survival in breast cancer patients, probably because they encourage an increase in the number cancer stem cells in breast tumors, according to a study carried out on mice by researchers from the Michigan Comprehensive Cancer Center, and published in the Proceedings of the National Academy of Sciences (early edition)... Alzheimer's Neurons Induced From Pluripotent Stem Cells Led by researchers at the University of California, San Diego School of Medicine, scientists have, for the first time, created stem cell-derived, in vitro models of sporadic and hereditary Alzheimer's disease (AD), using induced pluripotent stem cells from patients with the much-dreaded neurodegenerative disorder... Blood-Forming Stem Cells' Growth Identified Scientists with the new Children's Research Institute at UT Southwestern Medical Center have identified the environment in which blood-forming stem cells survive and thrive within the body, an important step toward increasing the safety and effectiveness of bone-marrow transplantation. Institute investigators led by Dr... Data For Adipose Stem Cell Heart Attack Trial Published In JACC Cytori Therapeutics (NASDAQ: CYTX) has announced the publication of previously reported six-month outcomes from APOLLO, the Company's European clinical trial evaluating adipose-derived stem and regenerative cells (ADRCs) in patients with acute myocardial infarction (heart attack or AMI), as Research Correspondence in the Journal of the American College of Cardiology... First Step In Strategy For Cell Replacement Therapy In Parkinson's Disease Induced pluripotent stem cells (iPSC) are a promising avenue for cell replacement therapy in neurologic diseases. For example, mouse and human iPSCs have been used to generate dopaminergic (DA) neurons that improve symptoms in rat Parkinson's disease models... Therapeutically Useful Stem Cell Derivatives In Need Of Stability Human stem cells capable of giving rise to any fetal or adult cell type are known as pluripotent stem cells. It is hoped that such cells, the most well known being human embryonic stem cells (hESCs), can be used to generate cell populations with therapeutic utility. In this context, neural derivatives of hESCs are being tested in clinical trials... Stem Cells Show Promise For Delivering Gene Therapy For Huntington's Disease A team of researchers at the UC Davis Institute for Regenerative Cures has developed a technique for using stem cells to deliver therapy that specifically targets the genetic abnormality found in Huntington's disease, a hereditary brain disorder that causes progressive uncontrolled movements, dementia and death... Stem Cell Treatment For Blindness Shows Promise In Trials The first published results of trials using cells derived from human embryonic stem cells appear to show they have passed an initial safety hurdle... Gene Critical To Sense Of Smell Found In Fruit Fly Fruit flies don't have noses, but a huge part of their brains is dedicated to processing smells. Flies probably rely on the sense of smell more than any other sense for essential activities such as finding mates and avoiding danger. UW-Madison researchers have discovered that a gene called distal-less is critical to the fly's ability to receive, process and respond to smells... Tumor Growth Not Halted By Cell Senescence A collaboration between a cancer biologist from the University of Milano and 2 physicists has shown that cell senescence occurs spontaneously in melanoma cells, but does not stop their growth Since cancer cells grow indefinitely, it is commonly believed that senescence could act as a barrier against tumor growth and potentially be used as a way to treat cancer... Brain Support Cells From Umbilical Cord Stem Cells For the first time ever, stem cells from umbilical cords have been converted into other types of cells, which may eventually lead to new treatment options for spinal cord injuries and multiple sclerosis, among other nervous system diseases... "Smart" Nanotherapeutics Developed That Deliver Drugs Directly To Pancreas A research collaboration between the Wyss Institute for Biologically Inspired Engineering at Harvard University and Children's Hospital Boston has developed "smart" injectable nanotherapeutics that can be programmed to selectively deliver drugs to the cells of the pancreas... Stem Cell Implants Help Heal Traumatic Brain Injury In The Lab For years, researchers seeking new therapies for traumatic brain injury have been tantalized by the results of animal experiments with stem cells. In numerous studies, stem cell implantation has substantially improved brain function in experimental animals with brain trauma. But just how these improvements occur has remained a mystery... Gene Crucial To Normal Development Of Lungs And Brain Identified By Scientists Scientists at the Salk Institute for Biological Studies have identified a gene that tells cells to develop multiple cilia, tiny hair-like structures that move fluids through the lungs and brain. The finding may help scientists generate new therapies that use stem cells to replace damaged tissues in the lung and other organs... Brain's Ability To Self-Repair Boosted By Natural Protein Researchers from the Medical Research Council (MRC) in the UK have found a protein made by blood vessels in the brain that could be a good candidate for regenerative therapies that stimulate the brain to repair itself after injury or disease. They write about their findings in the 9 January online issue of the Proceedings of the National Academy of Sciences... Type 1 Diabetes Reversed With Stem Cells From Cord Blood Stem cells from cord blood "re-educated" the immune system T cells of people with type 1 diabetes so their pancreas started producing insulin again, thereby reducing the amount of insulin they needed to inject.
