"It's probably will be much, much sooner than we anticipated. The science and technology develop so fast. So hopefully it's not going to be 20 years, hopefully within five, 10 years, we will have first therapeutic application of these cells."

STORYLINE:
American scientists at the Oregon National Primate Centre in Portland reported on Wednesday that they had
cloned embryos from a 9-year-old male monkey and derived stem cells from them, reaching a long-sought goal that may pay off someday in new treatments for people.
The work was published online by the journal Nature, which took the unusual step of asking another team of researchers to verify the work before publication.
That reflects the legacy of a spectacular fraud in stem cell research from South Korea several years ago.
The new work is important because someday researchers hope to use such a process in humans to make transplant tissue that's genetically matched to patients, thus avoiding the risk of rejection.
The scientists combined DNA from skin cells of the monkey with unfertilised monkey eggs that had their own DNA removed.
The eggs were then grown into early embryos, from which stem cells were removed.
In doing so, they reached a long-sought goal that may someday lead to new treatments for people.
The scientist behind the research, Shoukhrat Mitalipov, of the Oregon National Primate Research Centre said technology was helping to push the research forward, which would benefit society.
"It's probably will be much, much sooner than we anticipated. The science and technology develop so fast. So hopefully it's not going to be 20 years, hopefully within five, 10 years, we will have first therapeutic application of these cells," he said.
Mitalipov's team of researchers who've applied for a patent on their procedure, merged skin cells of a 9-year-old rhesus macaque male with unfertilised monkey eggs that had the DNA removed.
The eggs, now operating with DNA from the skin cells, grew into early embryos in the laboratory. Stem cells were recovered from these embryos.
Someday researchers hope to use such a process in humans to make transplant tissue that's genetically matched to patients, thus avoiding the risk of rejection.
However, there are many ethical and political issues to contend with from opposing quarters, not least from the US President George Bush who has twice vetoed a stem cell research bill.
But Mitalipov is standing by his research said he hopes society will eventually come round:
"If we prove that, you know, these embryonic stem cells have great potential in curing many, many diseases then I think the society will accept this as a medical treatment," he said.
The researchers warn that even if the procedure could be used to produce human stem cells, it's far too inefficient to be used in medicine.
Human unfertilised eggs are in short supply and are cumbersome to obtain. The monkey work required 304 eggs from 14 female macaques to produce just two batches of stem cells.
