Stem Cell Research

Stem cells are located deep down in our bone marrow. They have the incredible ability of “generating an endless supply of red cells, white cells, and platelets”(1). They have been called the “Mother of all blood cells” due to their ability to regenerate the entire blood supply of a persons body. Just to think that this is possible is actually pretty incredible. The man who claims to be responsible for the discovery of this gem is a immunologist from Stanford University named Irving Weissman, and his collaborators at SyStemix, (a biotech company that he cofounded in 1988, located in Palo Alto, CA). He and his company are so

One man, in particular, Jan Visser, developed a strategy for separating these stem cells from other cells in blood. He fine tuned his strategy by making small changes in what he was doing, which broke down the number of cells to smaller and smaller groups, until finally, he narrowed it down and he figured that there is approximately one stem cell per 10,000 cells. Visser had his original results published in the Journal of Experimental Medicine in 1984, and four years later, Weissman announced in the journal Science that he and his colleagues had found the mouse's stem cell. It was Weissman's article that drew headlines, while Visser's only drew polite praise. Visser notes ironically, The Journal of Experimental medicine is considered scientifically one of the best journals. Science is more popular.
It was the Weissman team that took a much more narrow approach to separating the cells, they used a variety of monoclonal antibodies, each with a specific ability to single out certain proteins on certain cells. In my opinion, this is how science works. Science is based on someone figuring something out, and another person comes along later and makes it better. It is called advancement. The problem with what Weissman did, was that he claimed all responsibility for discovering stem cells and separating cells and gave no credit to Visser or anyone else who had made huge leaps forward with the advancement of
