He added that coating the delivery particles with the proteins encoded by the five genes had the same effect.
Sundsmo said that colonies of iPS-like cells formed after about a week, contrasting Yamanaka's technique, which takes more than a
month to form colonies of iPS cells.
Most remarkably, he claimed that PrimeGen's method is much more efficient, forming about 1000 times as many colonies of reprogrammed
cells.
However, given previous claims in stem cell biology that have failed to stand up, other scientists are taking a cautious line.
"This is fascinating. But without more information, it's hard to know exactly how much they have done, New Scientist magazine quoted Arnold Kriegstein, head of developmental and stem cell biology
at the University of California, San Francisco, as saying.
Sundsmo said that the company is writing up scientific papers on the method, and plans to release more details at a stem cell
scientific meeting later this year.
He added that an independent lab has tested its cells and it has brought in top researchers to examine the results.
