New Stem Cells Technique Offers Hope for Kids With Immune Deficiency

For children born with immunodeficiencies, researchers may have found a better way for them to get the help they need from stem-cell transplants (…)

Children with primary immunodeficiencies have genetic defects in their immune system that leave them open to infection and other complications. Stem-cell transplants can replace the defective immune system with one derived from healthy donor bone marrow, but without a stem-cell transplant, many of these children might die, the researchers noted in a journal news release.

In order to create space for the donor stem cells and prevent rejection, the patient usually undergoes chemotherapy, radiotherapy or both. This

Autologous Stem Cell Transplants, Visible Progress in 8 of 10 Patients

Transplanting stem cells from one’s own bone marrow (autologous stem cell transplants) improves the symptoms of muscular sclerosis (MS), and in some cases the neurological disease actually regressed. These are the encouraging results obtained from a small study performed on 21 remittent MS patients by a group from the Northwestern University School of Medicine in Chicago and published in Lancet Neurology. “All of the patients,” said the neurologists, “witnessed an improvement in their conditions three years after the stem cell transplants were performed. Of these, 81pct benefited from visible

Study: Stem Cells Fight Multiple Sclerosis

The symptoms of multiple sclerosis could be reversed thanks to stem cell transplants from the patient’s own bone marrow, according to a study that will be published in March in Lancet Neurology by researchers from Northwestern University Feinberg School of Medicine in Chicago, who say that stem cell transplants could restore the immune system of patients suffering from the disease, stopping its evolution, and even causing its regression.

Multiple sclerosis is an autoimmune disease characterized by a defective immune system, which attacks the body’s own tissues in the central nervous system, and effects 57 thousand Italians. The disease

ISRAEL – Embryonic Stem Cell Transplant Causes Benign Tumors in 17 Year-Old Boy

Researchers using stem cells must work to make their treatments safer after a 17 year-old boy with a rare genetic disease in 2001 was cured with an embryonic stem cell transplant in Moscow, but then developed benign brain and spinal tumors four years later. According to ‘Plos Medicine’ magazine, Israeli doctors removed cancer from the boy, the tumors developed due to a stem cell treatment that he received.

ISRAEL – Embryonic pig stem cells against diabetes

A new experimental therapy to treat diabetes, which involves transplanting embryonic pig stem cells into the diseased tissue, is currently being researched. Experiments have been done on primates, but the results that have been obtained indicate that in the future the same technique could be applied to human beings. For many years, pig organs have been considered the most best match to be used in human transplants, but strong immune reactions and powerful combinations of anti-rejection drugs have always represented an important obstacle in their clinical use.

A study published in the
