PROVE MY STATEMENT WRONG!!!
Go back and look and prove THAT statement WRONG!
STAY ON TOPIC!!!!!!!!!!!!!!!!
How many times do I have to tell you? WE WOULD NOT HAVE THE ADULT STEM CELL MEDICINE TODAY IF WE WERE NOT CURRENTLY WORKING WITH ES CELLS! Get it? It's the foundation, without ES CELLS THERE IS NO CURRENT ADULT STEM CELL MEDICINE.
I'm going to have to give you a god damned biology lesson for you to understand this...
Stem cells are part of the germ line, they create all other cells. When they divide they create a copy of themselves (another stem) and a differentiated cell. These differentiated cells are specialized to do certain function (like, secrete a fluid). The most basic of the stem cells are the totipotent embryonic stem cells. THEY ARE THE ONLY CELLS THAT ARE TOTIPOTENT. Totipotent means that they can become ANY cell in the body. We lose these after we develop. All adult stem cells are pluripotent, meaning they can become a lot of different types of cells. For example, hemopoatetic stem cells can create a lot of different blood cells, mast, helper T, red, etc. But they cannot create neurons. ES cells can create both.
Now, these (both adult and embryonic) stem cells react to certain chemical and/or electrical signals that tell them what to become. We don't understand ALL of these signals, but a fair amount. We have also been able to cause certain pluripotent stem cells to cross their pluripotency border. We have been able to get that stem cell that makes blood cells to produce some tissue cells. But, the way we found this out was by experimenting with embryonic stem cells. It was the only method by which we could test and figure out which signals do what. We can test this signal on the totipotent cell and see what it becomes. We could also test this signal on each and ever type of adult cell, but it would take far more time than feasible because there are so many. Thus, experimentation with ES cells are vital to finding out what causes the pluripotent stem cells to differentiate. Once we figure this out, we can then use the specific adult cell to create what we want. Thus making ES cells the pillar of stem cell research.
Our most functional labs are those that have the help of federal funding. The business side of the lab focuses on using adult stem cells because they either cannot afford to do ES cell work or because they do not wish to risk their last few federally funded strains being infected. So we do whatever we can with the cheaper cells, after learning what we can do with them from ES cell work. Everything that can be done with adult stem cells, can be done with ES cells. Everything that can be done with ES cells cannot be done with all adult stem cells.
