our observations together with the experimental findings of others ( that fibroblastic stromal cells contribute to the hematopoietic inductive microenvironment , that hematopoietic stem cells are concentrated subosteally , that cells responsible for regeneration of the marrow stroma are derived from the endosteal layer , and that high concentrations of hematopoietic colony-stimulating factors are produced there ) indicate that the hematopoietic capacities of bone marrow may be regulated by blc .
