ITALY – Stem Cells. New Method to Combat Immunodeficiencies in Children at San Raffaele in Milan.

It was stunning to see them closed inside of those plastic bubbles, kept far from all external contact because their immune system does not react against any foreign antigens. Today scientists can say that ADA-SCID (adenosine deaminase deficiency), a serious combined immunodeficiency caused due to a lack of the adenosine deaminase enzyme, has been definitively defeated by gene therapy developed at San Raffaele of Milan.

The final study, which combined the conclusions of clinical studies, which began in 2000 on strategic therapies developed by the HSR-TIGET (San Raffaele Telethon Institute for Gene Therapy) group,

Predict graft-versus-host disease in men

If there’s one single image that universally connotes death, it’s that of a skeleton. But in the living human body, bones are a beehive of activity that, at the cellular level, is as lively and intricate as any dance troupe could perform.

Within the hollows of the long bones dwells a spongy tissue called marrow, which hosts stem cells responsible for the production of both red and a variety of white blood cells. The latter are the warriors, messengers, sentries and medics that compose our immune system. White blood cells defend against microbial invaders and scour our bodies for suspicious

New hope for diabetics after stem cell discovery

A DRUG said to cure diabetes could mean that sufferers will no longer need to take daily insulin injections.
The treatment uses stem cells made from human bone marrow and has been tested on patients suffering from Type 1 diabetes – which affects about 900,000 people in Britain.

Diabetes causes the immune system to attack the pancreas, the organ that makes insulin, which then controls blood-sugar levels.
Sufferers must take insulin injections to stay alive because if blood-sugar levels are allowed to rise too high or get too low, they could fall into a coma and die.
But early trials by American scientists

Stem cells could be the secret reason why breast is best

Breast milk, long revered for the nutritional advantages it gives a newborn, could be just as vital in terms of infant development, a leading scientist will claim this week. Up to three different types of stem cells have been discovered in breast milk, according to revolutionary new research.

Dr Mark Cregan, medical director at the Swiss healthcare and baby equipment company Medela, believes the existence of stem cells means breast milk could help a child “fulfil its genetic destiny”, with a mother’s mammary glands taking over from her placenta to guide infant development once her child is

Missing link between blood stem cells, immune system discovered

UCLA researchers have discovered a type of cell that is the “missing link” between bone marrow stem cells and all the cells of the human immune system, a finding that will lead to a greater understanding of how a healthy immune system is produced and how disease can lead to poor immune function.

The research was done using human bone marrow, which contains all the stem cells that produce blood during post-natal life.

“We felt it was especially important to do these studies using human bone marrow, as most research into the development of the immune system has used
