They had issues because some people did not understand or care that they had technology to create embryonic stem cell lines without destroying any embryos. That crowd did not care. And so their top scientist, who was a phenomenon in the space and had an immense amount of patents in the field of cell therapies and stem cells and cloning and induced pluripotent technologies and cell programming, was stalked by that crazy crowd and the government, while promising to open up the field of stem cell science, really did not do what everyone expected at the time. And then IPS or induced pluripotent stem cells became the rage, but they were defective at that time. Some people including the top scientist at Ocata, figured out ways to reprogram without using oncogenes (cancer genes), but the initial cells were all created basically by mutating normal cells and turning them into almost cancer cells or mutant cells. But the mania over avoiding pristine embryonic cells was so intense that it was basically irrational.
