USA – Stem Cell Research: New Experimental Techniques to Treat HIV-AIDS

Gerhard Bauer & Jan A. Nolta

A new experimental technique in the future will remove skin cells from HIV patients, manipulate the cells bringing them to a state similar to that of stem cells, and then re-implant them in the same patient to eliminate the virus. The technique is still in the experimental phase in mice, but according to Gerhard Bauer, presenting the initial results of his study today at the 50th American Society of Hematology Congress in San Francisco, it’s a possibility. Bauer has been working for more than 10 years on this technique together with

ITALY – Pisa. Hematopoietic stem cell collection center opens

The Pisa University Hospital has become part of the international network of hematopoietic stem cell transplant facilities (meaning they produce various blood components). The hospital was recently accredited by the Italian registry of bone marrow donors, which is part of the international network.

Pisa has become an important center for bone marrow collection for all potential donors in northwestern Italy.
On 20 April 2009, the first donation was carried out for a patient at the Udine University Hospital, and a second donation is being organized for a patient being treated at the Montpellier Hospital (France).

The hospital in Pisa received the

Stem Cell Survival Strategy Is Key to Blood and Immune System Health

Stem cells of the aging bone marrow recycle their own molecules to survive and keep replenishing the blood and immune systems as the body ages, researchers at UC San Francisco (UCSF) have discovered.

The recycling process, known as autophagy, or self-eating, involves reusing molecules and the chemical energy obtained from these molecules to withstand the killing effect of metabolic stress that intensifies as the body ages.

The discovery, reported online Feb. 6 in the journal Nature, showed that autophagy allows stem cells to avoid the alternative response to stress, which is programmed cellular suicide, in which cells that aren’t

Recovering From Radiation and Chemotherapy

Researchers at the University of California, San Diego School of Medicine report that a protein called beta-catenin plays a critical, and previously unappreciated, role in promoting recovery of stricken hematopoietic stem cells after radiation exposure.

The findings, published in the May 1 issue of Genes and Development, provide a new understanding of how radiation impacts cellular and molecular processes, but perhaps more importantly, they suggest new possibilities for improving hematopoietic stem cell regeneration in the bone marrow following cancer radiation treatment.

Ionizing radiation exposure – accidental or deliberate – can be fatal due to widespread destruction of hematopoietic stem cells, the

Wisconsin Stem Cell Symposium to focus on blood

World stem cell leaders will converge on Promega’s BioPharmaceutical
Technology Center in Fitchburg, Wisconsin, on April 30 for the 9th
Annual Wisconsin Stem Cell Symposium: From Stem Cells to Blood.

Coordinated by the nonprofit BioPharmaceutical Technology Center Institute, the University of Wisconsin-Madison Stem Cell and Regenerative Medicine Center
and the UW-Madison Blood Research Program, this year’s symposium is
focused on how the stem cells that give rise to blood develop and
function.

It will also look at the diversity of insights stem cell
studies have provided other fields.

Highlighted topics include genesis and regulation of progenitor cells
and hematopoietic stem cells, stem cell genomes/epigenomes, stem cell
microenvironment, and tumor initiating
