[Endosteal cells of the bone marrow stroma in human iliac bone]
Abstract:
The data on histological and electron microscopical investigation of the endosteal cells of the human iliac bone are presented. Three types of stromal elements in the endosteum, differing in their ultrastructural organization have been revealed. In the endosteal areas young hemopoietic cells are present, they are closely connected with the stroma. A suggestion is made on an important role of the endosteum in processes of proliferation and differentiation of hemopoietic predecessors.
