Cord blood donation program turns medical waste into a lifesaving resource

Leukemia, the most common form of childhood cancer, affects the blood-forming cells in the bone marrow. It is often treated with stem cell transplants that replace the patient’s bone marrow cells with stem cells donated by a healthy individual. Successful transplant depends on finding a donor who is a close genetic match to the patient. That’s a particular challenge for patients from racial and ethnic minority groups, who may die while waiting for a matching donor.

But a mostly-untapped source of genetically diverse stem cells is right under our noses: Blood left in the umbilical cord after a baby is

GREAT BRITAIN – Artificial type 0 blood thanks to embryonic stem cells

After making news on several occasions, scientists may have made a definitive breakthrough, with the first possible transfusion using blood obtained from embryonic stem cells possibly coming within the next three years. The transfusion would be done with type O blood, which can be donated to any patient, and would be obtained by researchers using excess embryos from assisted fertilization. The project, which will be led by Marc Turner of Edinburgh University, will also receive contributions from the Transfusion and Transplant Service of the British National Health Service, as well as the

ITALY – In 2008, 10,000 Couples Abroad To Store Umbilical Cord Stem Cells

A Swiss company present in Italy that collects and stores umbilical cord stem cells, about 10,000 Italian mothers by the end of the year will have deposited their children’s umbilical cord stem cells in foreign banks, double compared to 2007. They said, “Just two years ago about 1,500 families decided to deposit their children’s umbilical cord stem cells in banks. In 2007, requests for this service tripled, reaching 5,000 and in 2008. There will be about 10,000 new cryostorages in order to make stem cells available in the future (illegal in Italy).

Stem Cells with potential to become eggs found in ovaries

Researchers found stem cells in the ovaries of young women that have the potential to become healthy eggs. Applications of this discovery may help women have children that were once too old to or left infertile because of disease.

Natalie Melgar-Fetzer, a junior in ICS from Maryland said “It’s interesting because it can give women with reproductive problems the opportunity to have children. So many people want to have babies but can’t for whatever reason.”

Researchers have already created potentially viable eggs from these stem cells by adding a protein to them as well as a gene that makes jellyfish glow

Calorie Restriction and Skeletal Muscle Stem Cells

While looking for mechanisms that might be relevant to restoring regenerative potential in older skeletal muscle, HSCI Executive Committee member, Amy Wagers, PhD, and her team, thought about mechanisms that had been studied for a long time evolutionarily as regulating lifespan and longevity. One example of such a mechanism is reduced calorie intake in the absence of malnutrition, also know as calorie restriction, which has been show to extend lifespan in many organisms.

In order to address the question of whether calorie restriction could also affect skeletal muscle regeneration, Wagers and her colleagues placed mice for 12 weeks
