we postulate from our studies on semi-thin sections of undecalcified bm from healthy human fetuses , normal adults and patients with acute myeloid leukaemia ( aml ) and chronic granulocytic leukaemia ( cgl ) that the endosteal cells are the precursors of all haematopoietic cells in the bone marrow and are also capable of transformation into either stromal ( fibroblast-like cells ) or bone-related cells ( osteoblasts and osteoclasts ) .
