I did my PhD in cell biology a few years ago and I am seriously sceptical about the Kickstarter campaign. There are too many questions and way too few control experiments. What you can see about their preliminary research is the rotation device and the pictures of the cells. From what I have learned during my studies is that it is easy to kill cell cultures and it is difficult to compare different cell lines. For example, most cells need a very controlled environment (temperature, growth medium, pH, a specific amount of cells per area and not too many or too few neighbouring cells etc.) This rotation device appears to be at room temperature and creates a shear flow, which is enough to kill most cell cultures. The picture they show is not helpful at all, as they just show dying cells. As others stated: you need more control experiments. One would be to keekp a bottle of cells in the machine, without rotation. That's really cheap and easy to compare, which they did not. (not addressing the issue that that's not real microgravity) I hope to find time later to find their publications, until then I don't believe this to be real.

Edit: I cannot find anything that's even looking like research. News articles all referring Chou, but nothing to show for it. No paper or data. Now it looks even worse.
