There are ways for some genes(as far as we know) that are turned on(expressed) or turned off(suppressed)...there are chemical entities which can do this...different genes are turned on and off during embryogenesis depending on what the cell is going to be...amazing thing...most cells have the same complement of genes and chromosomes, but different parts of the genome are turned on or off to differentiate that cell to become a specific cell at a specific time. it is basically a 4d process...right info, right expression/suppression, right position in space, right timing. As soon as we unravel all the cues which set these processes in motion we may hope for some rejuvenation of damaged tissue...for now, we can try something’s and hope we discover something that works...but we cannot advance much further since knowledge is rascist!

Thank you.
