As we know, so many attempted Alzheimer's treatments haven't yet worked. But could a new type of cell get the job done?
In macaque monkeys, researchers at the University of Pittsburgh and colleagues successfully used stem cells to reverse sterility caused by cancer treatments, and the team used sperm from one of the treated animals to successfully fertilize a number of eggs. The hope is to eventually use the same treatment in young boys made infertile by chemotherapy, though the treatment itself carries cancer risks.
Duke Medicine scientists used induced pluripotent stem cells (iPSCs) from mice to build new cartilage viable enough to treat osteoarthritis and cartilage injuries. They hope to test their process next with human cells.
Cellular Dynamics International will supply stem cells to the National Institutes of Health Center for Regenerative Medicine for the next three years part of a new contract worth up to $7 million, the Wisconsin State Journal reports.
Israel's Pluristem Therapeutics says its stem cells drawn from discarded placentas have generated success both in vitro and in animal studies as a treatment to reduce fibrosis.
Scientists have successfully grown induced pluripotent stem cells from fibroblasts--cells that make connective tissue--collected from the scalps and brain linings of 146 human brain donors.
Researchers successfully used muscle tissue in adult mice to create neural-like stem cells, and they believe the finding could be a way to treat neurodegenerative diseases, brain tumors or brain and spinal cord injuries.
News that Japanese scientists successfully used mice stem cells to create eggs and then fertilized them to produce baby mice is a big enough breakthrough, representing the first successful use of stem cells to create a mammal. A team at Stanford University aims to take this even further, however, and create healthy human sperm from stem cells.
Two men--one in the United Kingdom and the other in Japan--are winners of the 2012 Nobel Prize in physiology or medicine for advances they've brought to stem cell research and cloning over 40 years of work in the field.
Athersys said its adult stem therapy for multiple sclerosis has produced lasting neurological improvements in recent animal studies and stopped the disease from progressing.
