Eyeroll. SO many things wrong here. A person isn't a cell. In fact, a person has a lot of cells, more than I can count on my fingers and toes (also, not by coincidence, made of cells). What works in culture doesn't always work in humans. What works in animals doesn't always work in humans. Let me give you a real world example. Someone once decided to study the effects of patient environment on recovering stroke patients. They found that after controlling for everything they could think to control for, if the patient simply had a window in her/his room, they tended to do better in recovery. Furthermore, if a tree lay outside that window, an even greater effect was observed. There's no laboratory basis for this observation. We didn't need a million dollar study to advance it. It's a simple, cheap, patient-centric approach to help people recover. But the "evidence" crowd would have you believe this is stupid. There are countless examples in medicine of similar phenomena. Because coffee enemas are stupid and baseless (so I'm told), that doesn't mean that all medicine has to advance from benchtop to preclinical studies to the clinic. That's one way, but it's not the only way.
