I originally had a theory based upon my theory ofPosition Relative Cellular Differentiation that if you could get an embryonic stem cell from a human adult, that you could then place that stem cell in a bath that resembled the nutrient complex of the zygote at very early stages of conception, then add constant stirring to that bath to prevent clumps of cells from forming, then maintain a steady flow of incoming fresh fluid that matches the nutrient rich influx of fluid into a zygote, and that would cause the stem cells to continue dividing indefinitely without differentiating. You could then bleed off the excess bath from the container and that bath would contain some waste chemicals and a steady flow of stem cells. I then read that the embryonic stem cells were separated from the nutrient rich bath by a layer of cells called the blastocyst. I thought that shot my theory to hell. Then I realized that all you had to do was compensate for the changes in chemical markers and nutrients that the stem cells see because of the blastocyst cells and as a result the bath would promote stem cell growth. This mirrors the fact that current stem cell growth methods include a layer of feeder cells on the actual nutrient substrate between the stem cells and the nutrients. So, once again, we need to map out the chemical marker production of cells relative to DNA so we can duplicate the effects of these blastocyst or feeder cells in the base bath mixture so that we can eliminate them from the growth process and get on with the mass production of genetically keyed stem cells that are necessary to correct things like the need for bone marrow transplants, cures for adult onset diabetes, etc.
