[Relationship between various stromal cells in long-term bone marrow culture]

In the present studies, the relationship and special junctions between various stromal cells in long term bone marrow culture were reported. The possible significance of these signs vis-a-vis the hemopoietic microenvironment were discussed. Fibronectin and thrombospondin were detected on the substratum and surface of the stromal cells using immunogold techniques. These adhesion proteins on the stromal cells might be important in cell-cell and cell-stroma connection.
