Stem Cell Treatments Normally Used for Cancer Patients are Helping Multiple Sclerosis Patients
Overview of Stem Cell Transplant for MS Patients
Recent reports from the British Broadcasting Corporation (BBC) highlight the transformative effects of stem cell transplant treatments originally used for cancer patients on individuals suffering from Multiple Sclerosis (MS) in the UK. According to a January 18, 2016 report, this innovative approach has shown promising results in restoring mobility and reversing disability in MS patients.
Autologous Hematopoietic Stem Cell Transplantation (HSCT)
The treatment, known as autologous hematopoietic stem cell transplantation (HSCT), involves the infusion of the patient’s own stem cells harvested from bone marrow. This procedure aims to rebuild the immune system, potentially resetting it to a state before it caused MS-related damage.
Testimonials and Clinical Results
Professors Basil Sharrack and John Snowden from Sheffield’s Royal Hallamshire Hospital emphasize the profound impact of HSCT on MS patients. Patients like Steven Storey, who experienced significant disability progression prior to treatment, have reported remarkable improvements in mobility and quality of life post-transplant.
Steven Storey’s Journey
Steven Storey, diagnosed with MS in 2013, transitioned from being an athlete to wheelchair-bound within a year. Following HSCT, he regained movement in his toes within days and achieved unaided standing after four months. While still using a wheelchair, Storey’s progress is described as astounding, allowing him to swim, cycle, and aspire to walk again.
The MIST International Clinical Trial
The Royal Hallamshire Hospital, alongside institutions in the US, Sweden, and Brazil, participates in the MIST trial. This international study evaluates the long-term benefits of HSCT on patients with relapsing-remitting MS (RRMS), aiming to establish its efficacy as a standard treatment option.
Future Prospects and Research
Prof Richard Burt of Northwestern University leads the MIST trial, pioneering HSCT for MS treatment since 1995. Despite challenges from the pharmaceutical and academic sectors, early studies have shown promising neurological disability reductions, with ongoing research poised to validate these findings further.
Conclusion and Outlook
As ongoing research continues to validate the potential of HSCT in treating MS, stakeholders like Emma Gray, M.D., head of clinical trials at the UK’s MS Society, emphasize its life-changing impacts highlighted by real patient experiences. The outcomes from the MIST trial, expected in 2018, could potentially integrate HSCT into the standard healthcare protocols for MS patients in the UK.

Our Friend MSCs (Mesenchymal Stem Cells)—Bringing New Life to Old Bones
Understanding MSCs and Their Role in Osteoporosis Treatment
Researchers from the University of Toronto and The Ottawa Hospital have explored the potential of mesenchymal stem cells (MSCs) in treating osteoporosis. MSCs are versatile stromal cells capable of differentiating into bone cells (osteoblasts), cartilage cells (chondrocytes), muscle cells (myocytes), and fat cells (adipocytes).
Research Insights: MSCs Reverse Osteoporosis in Mice
In a groundbreaking study published in Stem Cells Translational Medicine, researchers injected healthy MSCs into mice with osteoporosis. Over six months—a significant period in a mouse’s lifespan—the damaged, brittle bones of the mice were replaced with healthy bone tissue. This restoration underscores the regenerative potential of MSCs in treating bone disorders.
Clinical Applications and Future Directions
This discovery raises hopes for new osteoporosis treatments in humans. Early trials involving elderly patients in the US have shown promising results, with ongoing studies assessing improvements in bone health through biological markers in blood samples.
The Global Impact of Osteoporosis
Globally, over 200 million people suffer from postmenopausal or age-related osteoporosis, leading to approximately 8.9 million bone fractures annually. Current treatments, like Teriparatide, offer temporary relief, highlighting the urgent need for more effective, long-term solutions.
