Allahu Akbar!

Lalu bukankah sudah saatnya orang Islam sadar bahwa ada yagn

Stem cells tailored to patients
South Korean scientists say they have made stem cells tailored
to match the individual for the first time.
Each of the 11 new stem cell lines that they made were created
by taking genetic material from the patient and putting it into a
donated egg.
The resultant cells were a perfect match for the individual and
could mean treatments for diseases like diabetes without problems
of rejection.
The study, published in Science, has been hailed as a major
advance.
Meanwhile, UK scientists at Newcastle University announced they
had successfully produced a cloned embryo using donated eggs and
genetic material from stem cells.
It really is an advance Professor Chris Higgins from the UK
Medical Research Council
Although a long way behind the Korean research, it was the first
time a human cloned embryo had been created in Britain.
Critics said these "cloning" techniques are unethical.
Hurdles
Experts warned that there was a risk the cells could become
cancerous.
And the Korean team admits much work is needed before stem cell
techniques can be perfected.
The stem cell lines produced by the Koreans from patients with
disease will likely also display some of the characteristics of
that disease.
Stem cell milestones
1960s: Research begins on stem cells taken from adult tissue
1968: Adult stem cells used to treat immunodeficient patient
1998: US scientists grow stem cells from human embryos and germ
cells, establishing cell lines still in use today
2001: Embryonic stem cell turned into a blood cell
2004: South Korean scientists clone 30 human embryos and develop
them over several days
2005: Korean team develops stem cells tailored to match
individual patients
In some cases, the cells might need to be manipulated before
being used as a treatment, said Dr Gerald Schatten, from the
University of Pittsburgh, US, who worked with the Seoul National
University team.
Researchers will also need to develop ways to efficiently direct
the growth of stem cells into stable cell types, said Professor
Woo Suk Hwang and his colleagues who successfully cloned human
embryos last year.
"Scientists must also find a way to remove the remaining animal
components from the laboratory procedures," they said.
Currently, scientists use animal enzymes to isolate the cells
needed for such research.
They also stressed that the technique should not be used to make
genetically identical babies - called reproductive cloning.
The technique
Stem cells are primitive "master" cells that can be programmed
to become many kinds of tissue.
To make them patient-specific, the researchers took DNA from the
skin cells of volunteers and put this genetic material into
donated human eggs which had had their own genetic material
removed.
These eggs were grown to a very early stage of embryo
development, around six days, when they were still just small
balls of cells. The scientists then extracted the stem cells.
Cloning for research purposes is profoundly unethical Julia
Millington of the ProLife Alliance
When the researchers examined them in the laboratory, the stem
cells appeared to be immunologically compatible to the individual
who donated the DNA.
Professor Chris Higgins, from the UK Medical Research Council,
said: "It really is an advance. It offers the possibility of stem
cell therapies without rejection.
"Also, the scientists have improved their technique and
reliability of stem cell transfer."
Professor Ian Wilmut, from the Roslin Institute in Edinburgh and
creator of Dolly the sheep, said: "These new observations make a
very significant and important step forward toward the use of
cells from cloned human embryos for research and therapy."
Roger Pedersen, Professor of Regenerative Medicine, University
of Cambridge, said the work provided "ample evidence" for the
feasibility of replacing the genome of a human egg with that of
an adult body cell.
HAVE YOUR SAY
Human cloning is essentially inevitable, and we would do well to
embrace its great prospects Robert Yang, California, USA
And Professor Alison Murdoch, Chair of the British Fertility
Society, and Dr Miodrag Stojkovic, Deputy Director of Centre for
Stem Cell Biology and Developmental Genetics in Newcastle, said:
"We are delighted.
"The promise of new treatments based on stem cell technology is
moving nearer to becoming a realistic possibility."
But Julia Millington, of the ProLife Alliance in the UK, said:
"Cloning for research purposes, which involves the manufacture
of human embryos destined for experimentation and subsequent
destruction, is profoundly unethical.
"The manufacture and destruction of one cloned embryo is one too
many, regardless of the number of eggs that are required.
"Experimentation upon human life at any stage of development has
no place in a civilised society."
Dr Richard Nicholson, editor of the Bulletin of Medical Ethics,
said: "I have considerable concerns. A large proportion of the
population believes that embryos are a form of human life and
that one is killing human life in order to produce these stem
cell lines.
"There is an alternative, which is to explore further what we
can do with adult stem cells obtained from places like the bone
marrow."
Dr Donald Bruce, Director of the Society Religion and Technology
Project of the Church of Scotland, said: "The idea of creating
cloned embryos to provide genetically matched replacement cells
for all patients with diabetes and other degenerative diseases
would require millions of donated human eggs in the UK alone.
That is not a likely prospect."
