Haruko Obokata, the embattled researcher at scandal-hit Riken, will comply with the institute's call for her to participate in an experiment to verify if STAP cells really exist, her lawyer said Tuesday.

"We should wait for Riken's official announcement, but Ms. Obokata is an employee of Riken and she will comply with its instruction," lawyer Hideo Miki told reporters in Osaka.

On Monday, the chairman of an outside panel to Riken said it is arranging to call on the lab to have the 30-year-old scientist participate in its experiment.
