[Structure and function of bone marrow environment].
Bone marrow and spleen are the major hematopoietic tissue in adult mice. However, little is known about the specific mechanism regulating hematopoiesis within these tissues. Since Dexter et al. first described conditions to maintain bone marrow hematopoiesis, long term bone marrow culture (LTBMC) has been developed in order to analyze the mechanism of the maintenance of proliferation and differentiation of hematopoietic stem cells in vitro. Furthermore, several stromal cell lines which are able to support the growth and differentiation of hematopoietic lineage, has been established from LTBMC. Although it is well known that bone marrow stromal cell lines are able to produce colony stimulating factors, it has been suggested that the stromal cell factors which involve membrane bound moieties must have a key role in the regulation of hematopoiesis. We expect that monoclonal antibodies to the surface of bone marrow stromal cells could detect such a critical stroma-associated protein that bounds the cell surface of the bone marrow stroma.
