QUOTE(b3ta @ Jun 26 2009, 02:05 AM) 1 thing about cloning organs, it doesnt seem to me as easy as it sounds. say u want to clone a liver, how do you make the cell grow into a liver? usual sperm and egg when combined grow into a zygote which gradually grows into a human being where its cells undergo differentiation to form different working (sometimes not) organs to sustain life. the question is, how do you make the cloned cell turn into a liver, and how do u sustain the liver's growth without all other supporting organs of the human body? read up on stem cells.basically, during our embryo stage, all cells are the same, there is no brain cell/muscle cell/skin cell etc. there is just cell. with the correct signals, these cells undergo specialization to be come whatever cell needed. theoretically (practically??) all you need is to get some stem cells, put them in a lab environment, provide nutrient, input signal, and viola - new organ then put in patient |
