Using donor stem cells to treat spinal cord injury

Published: August 28, 2017 | Category: News

Immune cells populating spinal cord after injury affect ability of stem cells to promote recovery

A new study in mice published in The Journal of Neuroscience details a potential therapeutic strategy that uses stem cells to promote recovery of motor activity after spinal cord injury.

The transplantation of neural stem cells could help promote repair of an injured spinal cord, but the interaction between donor cells and the resident cells that are part of the body’s immune response to injury is not well understood. Continue Reading »

It’s Not a Rat’s Race for Human Stem Cells Grafted to Repair Spinal Cord Injuries

Published: August 28, 2017 | Category: News

Lengthy study finds that implanted neural stem cells grow slow and steady, and success needs to be measured accordingly

More than one-and-a-half years after implantation, researchers at University of California San Diego School of Medicine and the San Diego Veterans Administration Medical Center report that human neural stem cells (NSCs) grafted into spinal cord injuries in laboratory rats displayed continued growth and maturity, with functional recovery beginning one year after grafting.

You might feel a bit down if you watch the news. Who wouldn’t?

Angry people might be grabbing headlines and making you wonder about the future, but the antidote is all around you.

Talk to some of your neighbors. Chances are, no matter what they look like or where they’re originally from, you’ll find they’re actually pretty decent people — just like you.

The little improvements we all try to make may not register much, but the accumulation of them all eventually does. Continue Reading »

Asterias Biotherapeutics Receives FDA Clearance to Enroll C-4 Patients in SCiStar Study

The future of stem cells: tackling hype versus hope

Published: January 28, 2017 | Category: News

Professor Alan Mackay-SimControversy surrounds the link between Australian of the Year Alan Mackay Sim’s research and a Polish team who restored mobility for a paraplegic man.

For many people suffering from disabling conditions, such as Parkinson’s disease, spinal injury and paralysis, multiple sclerosis, macular degeneration, heart disease, renal failure and even cancer, announcements in the press around breakthroughs in stem cell research undoubtedly bring hope.

The challenge remains how to accurately communicate what is genuinely possible in terms of therapies and what we scientists hope might be possible but do not yet have strong evidence for. Continue Reading »

Generating improvement in spinal cord injuries

Early clinical trial results announced offer new hope in regenerative medicine

A new therapy to treat spinal cord injuries in people who have lost all motor and sensory function below the injury site shows additional motor function improvement at 6-months and 9-months following treatment with 10 million AST-OPC1. The positive efficacy results from an ongoing research study were announced on Jan. 24 in a conference held by Asterias Biotherapeutics, Inc., the biotechnology company that manufactures AST-OPC1.

What are stem cells and how will they be used to treat the world’s most debilitating diseases?

Published: January 12, 2017 | Category: Answers

Stem cell research is often controversial but it has also led to incredible medical progress in recent years.

Stem cell research is at defining moment. Although it can be controversial and does raise a lot of important ethical issues, this area of medical science has been characterised by a number of important advances, ever since the first embryonic stem cells were isolated from mice in the 1980s. In the near future, it could reshape the way we treat some of the world’s most debilitating diseases.

Stem cells have already been used as treatment for a number of years – think bone marrow transplant – and they have the potential to help with many other medical conditions. Continue Reading »

Human Neuron Transplants Treat Spinal Cord Injury in Mice

Published: September 22, 2016 | Category: News

mge_spheroidsChronic pain and loss of bladder control are among the most devastating consequences of spinal cord injury, rated by many patients as a higher priority for treatment than paralysis or numbness. Now a UC San Francisco team has transplanted immature human neurons into mice with spinal cord injuries, and shown that the cells successfully wire up with the damaged spinal cord to improve bladder control and reduce pain. This is a key step towards developing cell therapies for spinal cord injury in humans, say the researchers, who are currently working to develop the technique for future clinical trials.

Asterias stem cell therapy shows promise in spinal cord paralysis: U.S. study

Published: September 14, 2016 | Category: News

asterias-biotherapeuticsAn experimental stem cell therapy developed by Asterias Biotherapeutics restored some movement to patients paralyzed by recent spinal cord injuries, according to interim data from a small study being presented on Wednesday.

One of the five patients in the trial regained use of both arms and hands, and is now able to feed himself, send texts on a phone and operate a wheelchair, the Fremont, California-based company said.

Three months after the cells were implanted, the study met its efficacy goal of two patients regaining return of two motor levels of functioning on at least one side of their body, the company said.

All five people in the study have experienced some upper extremity improvement so far, Asterias said. Continue Reading »
