Israeli Team Discovers Stem Cell “Bodyguards”

Published: October 31st, 2012

A research team headed by Professor Tsvee Lapidot of Israel’s Weizmann Institute’s immunology Department has discovered that the body’s precious stem cells – special bodies which can morph into many different types in order to provide vital services to the body in cases of need – have a little help in the immune system.
According to the paper, reported on by Israel21c, stem cells have backup from a sub-group of activated immune cells whose sole purpose is to defend them.
While the presence of mesenchymal cells – cells which provide support to stem cells in order to keep them healthy and strong – was already known, Dr. Lapidot’s team discovered that a subgroup of cells exists which prevent the differentiation of stem cells, secreting prostaglandins which preserve the youthfulness of the stem cells and prevent them from turning into anything else – also helping them survive chemotherapy or respond to infections.
Lapidot’s study further showed that introducing prostaglandin treatments can improve the quality and increase the number of the stem cells, an important discovery which may impact the strength and amount of cures to patients with leukemia.

"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.
 
There is nothing glorious about what our ancestors call history, 
it is simply a succession of mistakes, intolerances and violations.
 
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.

WARNING FROM RAEL: For those who don't use their intelligence at its
full capacity, the label "selected by RAEL" on some articles does not
mean that I agree with their content or support it. "Selected by RAEL"
means that I believe it is important for the people of this planet to
know about what people think or do, even when what they think or do is
completely stupid and against our philosophy. When I selected articles
in the past about stupid Christian fundamentalists in America praying
for rain, I am sure no Rael-Science reader was stupid enough to
believe that I was supporting praying to change the weather. So, when
I select articles which are in favor of drugs, anti-semitic,
anti-Jewish, racist, revisionist, or inciting hatred against any group
or religion, or any other stupid article, it does not mean that I
support them. It just means that it is important for all human beings
to know about them. Common sense, which is usually very good among our
readers, is good enough to understand that. When, like in the recent
articles on drug decriminalization, it is necessary to make it
clearer, I add a comment, which in this case was very clear: I support
decriminalizing all drugs, as it is stupid to throw depressed and sad
people (as only depressed and sad people use drugs) in prison and ruin
their life with a criminal record. That does not mean that there is
any change to the Message which says clearly that we must not use any
drug except for medical purposes. The same applies to the freedom of
expression which must be absolute. That does not mean again of course
that I agree with anti-Jews, antisemites, racists of any kind or
anti-Raelians. But by knowing your enemies or the enemies of your
values, you are better equipped to fight them. With love and respect
of course, and with the wonderful sentence of the French philosopher
Voltaire in mind: "I disapprove of what you say, but I will defend to
the death your right to say it".
