"nature" also retracted her work. riken allowed obokata to start conducting experiments in july to try to reproduce the results she described in her thesis. they gave her a lab equipped with surveillance cameras. they said obokata followed her method 48 times. but she failed to reproduce the cells by the end of november deadline.

they said stap cells were easy to produce. but scientists around the world reported they could not replicate the process. a panel of experts was set up to investigate the matter. they examined the material in the lab and the data used in the papers. >> translator: all the cells she said she created were actually embryonic stem cells. >> es cells are another type of cells. they're commonly used in labs around the globe. investigators suspect someone may have deliberately introduced them into the experiment but have no way to determine who might have done it. she denies responsibility. >> translator: she says she never mixed in the es cells. she was very consistent in her remarks. >> the investigators also identified two fresh instances in which she fabricated data, in addition to other two cases that were already known. analysts say she will face severe scrutiny because the supervisors failed to notice the flaws in her research. >>> government officials have compiled measures aimed at following through on a promise. prime minis
