I hate to admit it but I agree with you. He might actually help people in that one regard.
Why do cultured human cells have to go through long FDA trials anyway? Cultured cells are exact copies of cells that were taken from inside of human beings so of course they aren't toxic. I do understand that there's concern about the medium that the cells are cultured in, but aren't the cultured cells washed thoroughly to eliminate the medium before the cells are injected into patients?
Because even during normal cell division there are mutations that can lead to cancerous cells, artificially culturing may induce more of these mutated cells.
