TOKYO (AFP) - A co-author of a Japanese study that promised a revolutionary way to create stem cells has called for the headline-grabbing research to be retracted over claims its data was faulty.

The findings, published by Japanese researcher Haruko Obokata and US-based scientists in the January edition of British journal Nature, outlined a simple and low-tech approach in the quest to grow transplant tissue in the lab.

But it has faced hard questions as the Japanese research institute that sponsored the study launched a probe last month over the credibility of data used to reach the explosive findings.

At issue are allegations that researchers used erroneous image data for the high-profile Nature article.
