ITALY – Tumor Institute: safer stem cell transplants

Fondazione IRCCS Istituto Nazionale Tumori di Milano

Methods to provide safer stem cell transplants to individuals who are not completely compatible with the donor are being developed. Encouraging results have come from a post-transplant cellular therapy, which strengthens the immune system against viral infections and tumors, developed for the first time at the National Tumor Institute (INT) in Milan. The INT conducted the first phase I-II study in the world, published in ‘Blood’, whose main objective was to assess the use of a low dose radiochemotherapy, followed by low dose post-transplant infusions CD8-depleted donor lymphocytes after

Stem Cells Treat MS

Promising results from a small study may offer hope for the treatment of multiple sclerosis (MS).

Researchers from the University of California – San Diego report dramatic improvement after treating MS patients with stromal vascular fraction (SVF) stem cells from a patient’s own body fat. They say the SVF therapy can limit the body’s immune system reaction and promote the growth of new myelin – the fatty “insulation” on axons in the brain, which breaks down in patients with MS.

“None of the presently available MS treatments selectively inhibit the immune attack against the nervous system, nor do they

Starving causes restoration of stem cells in immune system

In the first evidence of a natural intervention triggering stem cell-based regeneration of an organ or system, a study shows that cycles of prolonged fasting not only protect against immune system damage — a major side effect of chemotherapy — but also induce immune system regeneration, shifting stem cells from a dormant state to a state of self-renewal.

In both mice and a Phase 1 human clinical trial, long periods of not eating significantly lowered white blood cell counts. In mice, fasting cycles then “flipped a regenerative switch,” changing the signaling pathways for hematopoietic stem cells, which are responsible for

USA – Stem cells self transplant: obvious improvements for 8 patients on 10

Bone marrow stem cells self transplant can reduce Multiple Sclerosis (MS) symptoms, and make the disease regress in some cases.
These are the hopeful results from a research on 21 patients diseased by MS, made by the Chicago Northwestern University School of Medicine and published on Lancet Neurology. “Since 3 years from self transplant all the patients watch their conditions better.”

Since these results, doctors decided to make a bigger research involving more MS diseased people and comparing new therapy’s results with olds’ ones.
The experiment is about taking marrow stem cells and then treating them to remove ill lymphocytes which attack

Stem cells tolerated by immune system

Many of us know by now that stem cells are remarkably fluid in the types of cells they can become. But this fluidity, or pluripotency, comes with a price. Several studies have shown that the body’s immune system will attack and reject even genetically identical transplanted stem cells, making it difficult to envision their usefulness for long-term therapies.

Now Stanford cardiologist Joseph Wu, MD, PhD, and his colleagues have shown that coaxing the stem cells to become more-specialized (a process known as differentiation) before transplantation allows the body to recognize and tolerate the cells. Their research was published today in
