Natural cure: Scientists create stem cell contact lens
Published: 07 December, 2012, 05:32
Researchers have found a better and a cheaper way to restore human sight by implanting a contact lens containing stem cells that will repair the human cornea.
Scientists from the University of Sheffield hope that the biodegradable implant disc's stem cells will multiply in the eye, thus rebuilding the transparent layer on the front of the eye, known as the cornea, the degradation of which is one of the major causes of blindness in the world, a study published in Acta Biomaterialia journal revealed.
Since stem cells have the ability to renew themselves through mitotic cell division and differentiation into a diverse range of specialized cell types, scientists hope that it will allow the eye to heal naturally as new implants are designed to form thin membranes by grafting the cells onto the eye itself.
Traditional treatment for cornea damage includes transplanting stem cells into the eye using donated human membranes. But in some cases this procedure fails, as in time the repaired eyes lose the retention of these stem cells, which are required to carry out repairs of the cornea.
What makes the new research different is that the new biodegradable lens contains small pockets of stem cells that protect them and serve as a constant repair utility.
"The material across the center of the disc is thinner than the ring, so it will biodegrade more quickly, allowing the stem cells to proliferate across the surface of the eye to repair the cornea," Ílida Ortega Asencio, from Sheffield’s Faculty of Engineering, was quoted as saying in Daily Mail.
Without stem cells, thick white scar tissue develops in the cornea, causing partial or complete sight loss.
The clinical trials are expected to begin in India as "the overall treatment using these discs will not only be better than current treatments, it will be cheaper as well," Frederick Claeyssens from University of Sheffield said.

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,
anti-Semites, 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".

"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.
