Scientists have grown stem cells from adults using cloning techniques for the first time — bringing them closer to developing patient-specific lines of cells that can be used to treat a whole host of ailments, from heart disease to blindness. Read full article >>
This is a step toward being able to regenerate replacements for diseased or damaged cells. In this case, cells from a 35-year-old man and a 75-year-old man were used to generate two separate lines of stem cells. The process, known as nuclear transfer, involves taking the DNA from a donor and inserting it into an […]
Technique may help with therapies, but is also used to clone animals.
Stem cells in bone marrow need to produce hydrogen sulfide in order to properly multiply and form bone tissue, according to a new study. Researchers demonstrated that mice's osteoporosis-like condition could be rescued by administering small molecules that release hydrogen sulfide inside the body. Show More Summary
This comes a year after researchers created the first early-stage human clones derived from infant and fetal cells. For the first time, scientists have created early-stage embryos using cloned cells from adults. Read Full Story
Scientists have moved a step closer to the goal of creating stem cells perfectly matched to a patient's DNA in order to treat diseases, they announced on Thursday, creating patient-specific cell lines out of the skin cells of two adult men.
Johns Hopkins researchers have discovered an unexpected phenomenon in the organs that produce sperm in fruit flies: When a certain kind of stem cell is killed off experimentally, another group of non-stem cells can come out of retirement to replace them. read more
Stem cells in bone marrow need to produce hydrogen sulfide in order to properly multiply and form bone tissue, according to a new study from the Center for Craniofacial Molecular Biology at the Herman Ostrow School of Dentistry of USC. Professor...Show More Summary
In what may be another step forward in treating spinal cord injuries, a safety trial will begin this year on the practice of injecting stem cells directly into the injury site, Neuralstem Inc. announced Wednesday. The Maryland company said the University of California, San Diego's Institutional Review Board had approved its clinical trial protocol, which also […]
Tissue engineering has been used to construct natural esophagi, which in combination with bone marrow stem cells have been safely and effectively transplanted in rats. The study shows that the transplanted organs remain patent and display regeneration of nerves, muscles, epithelial cells and blood vessels.
April 15, 2014, Irvine, Calif. — UC Irvine neurobiologists have found that genetically modified neural stem cells show positive results when transplanted into the brains of mice with the symptoms and pathology of Alzheimer's disease....Show More Summary
Tissue engineering has been used to construct natural oesophagi, which in combination with bone marrow stem cells have been safely and effectively transplanted in rats. The study, published in Nature Communications, shows that the transplanted organs remain patent and display regeneration of nerves, muscles, epithelial cells and blood vessels. read more
The artificial blood cells are made from adult skin or blood cells which have been hacked to become pluripotent stem cells. They're going to begin human trials in 2016, injecting the artificial blood into patients. They'll be making type O...
Stem cells are highly promising for the treatment of everything from HIV to leukemia to baldness. In many cases, however, a great number of them must be used in order have a noticeable effect, which makes treatments impractical or expensive. Show More Summary
Researchers in the UK have developed a technique to culture universal type-O blood from stem cells. It's the first time scientists have manufactured blood to the appropriate quality and safety standards for transfusion into a human being. It's a breakthrough that could eventually lead to the mass production of blood. Read more...
Scientists at the University of Edenburgh are testing artificial blood that could one day be used in transfusions. The process involves using adult skin or blood cells that have been genetically modified into stem cells, known as induced pluripotent stem (iPS) cells. These iPS cells are then cultured in biologic conditions that mimic the human […]
ANN ARBOR—The sponginess of the environment where human embryonic stem cells are growing affects the type of specialized cells they eventually become, a University of Michigan study shows. The researchers coaxed human embryonic stemShow More Summary
A team of scientists has successfully implanted lady-parts cultivated from stem cells into four women born without them: The women, who were between 13 and 18 at the time of the surgery, were all born with a rare genetic condition called Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH) — a condition that causes about one in 4,500 girls to be born with either […]
