Is it possible to keep only a,bone that has bone marrow that produces white cells that produce the antibody? It would be less creepy, but white cell maturation

Is it possible to keep only a,bone that has bone marrow that produces white cells that produce the antibody? It would be less creepy, but white cell maturation is not easy, so I guess there are many problems I don't imagine. But there is also monoclonal antibodies for cancer, and this antibody production looks somewhat similar.
