Stem cell shield may protect body from chemotherapy side effects

Washington State University researchers provided computer analyses for a new gene therapy study published in Science Translational Medicine.

The study – conducted by the Fred Hutchinson Cancer Research Center in Seattle and published May 9 – found stem cell gene therapy could protect blood cells from damage by chemotherapy in patients suffering from glioblastoma (malignant brain tumors), thereby extending life expectancy.

The WSU laboratory of co-author Grant D. Trobridge, assistant professor of pharmaceutical sciences, developed bioinformatics software that aided the Fred Hutchinson researchers in evaluating the safety of the procedure. The approach was to remove blood stem cells, add a gene

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

ITALY – Undersecretary Fazio: against freedom of choice for autologous conservation of children’s stem cells by parents

Image via Wikipedia

Italian Welfare Undersecretary Ferruccio Fazio disapproves of private biobanks and is clearly in favor of the “allogenic” conservation of umbilical cord stem cells, meaning the conservation of stem cells saved for the exclusive use of the donor-patient. Speaking about a government report on “the appropriate use of umbilical cord stem cells”, Fazio outlined the government’s approach on the issue. A few weeks after a ministerial decree dictating new regulations for umbilical cord conservation, Fazio explained autologous donation, meaning conservation of stem cells for yourself, “is not only less useful, but also less efficient as

Schwartz ‘doing OK’ after stem cell transplant

Mandi Schwartz ’11 completed a crucial step in her battle with leukemia Wednesday afternoon.

The women’s hockey player received a long-awaited stem cell transplant at about 3:30 p.m. local time at the inpatient transplant unit of the Seattle Cancer Care Alliance at the University of Washington Medical Center. The procedure took 32 minutes and there were no complications, said Dean Forbes, a spokesman for the cancer center.

Schwartz, a native of Saskatchewan, Canada has been in and out of chemotherapy for more than 20 months since first being diagnosed with acute myeloid leukemia in December 2008. After months of searching for

ITALY – Role of Stem Cells in Thyroid Tumors Discovered

Stem cells could be responsible for some forms of aggressive thyroid tumors (ATC, anaplastic thyroid carcinoma). The discovery was made by a young group of biotechnologists, biologists, and doctors from the Endocrinology department of the General Hospital of the University of Palermo. In the study, published in Plos One, the researchers described a subset of tumor stem cells that were able to proliferate continuously and may be responsible for uncontrolled tumor growth. These cells are resistant to chemotherapy and explain why ATC is so highly fatal in such a short period of time. The
