New research from the University of Gothenburg in Sweden appears to rule out the possibility that ovarian stem cells exist. This is a direct contradiction of previous research released in February from Massachusetts General Hospital, which concludes that stem cells could be harvested from a woman's ovaries and morphed into functional eggs.
A group of Canadian academics working in tandem with a J&J research team have claimed a breakthrough success, reversing diabetes in mice through human stem cell transplants.
Plenty of drug developers and scientists are trying to develop treatments that can successfully cross the elusive blood-brain barrier to combat Alzheimer's and other neurological disorders. One thing that could help their long-term efforts: Researchers at the University of Wisconsin-Madison used embryonic and induced pluripotent stem cells to create endothelial cells in the lab that help form that barrier in the body.
One of the challenges with testing stem cells as treatments is that they are hard to track in the body, to clearly determine if they've survived implantation, reached where they were supposed to go or strayed somewhere else. University of Liverpool researchers in the U.K. believe that they've solved the problem, and their breakthrough study is published in the journal ACS Nano.
Pluristem Therapeutics' ($PSTI) special stem cells drawn from discarded placentas have shown major promise in a preclinical study. As the company announced today, they spurred hematopoietic stem cells to grow bone marrow in mice after their injection into muscle.
By becoming dormant, skeletal muscle stem cells can survive in a human body after a person dies, for a good 17 days after the fact. During that time, it turns out, they're still viable enough to be revived and then subdivide into workable cells, Fabrice Chretien of the Pasteur Institute in Paris and his colleagues have discovered.
Stem cell research pioneer Shinya Yamanaka is sharing this year's $1.5 million Millennium Technology Prize with Linus Torvalds, the creator of Linux.
Armed with a new $6.8 million grant from the U.K.'s Wellcome Trust, Australian scientists are fine-tuning a drug designed to stop cancer patients from rejecting bone marrow transplants. Assuming they proceed on schedule, they hope to start human clinical trials by 2016, Sky News reports.
A newly discovered type of stem cell--multipotent vascular stem cells--may actually be the real factor behind vascular disease and the resulting heart attacks and strokes it typically can cause, University of California-Berkeley researchers have discovered.
Northwestern University scientists believe they have found a way to successfully use nanotechnology to directly induce stem cells to morph into bone cells, essentially on command.
