since we could not detect smig+/tdt+ cells in bone marrow samples from adult healthy volunteers and from 10 children with all in complete remission , we conclude that tdt+ b-all cells may not have a normal counterpart in bone marrow or represent a malignant counterpart of a very rare cell in an intermediate differentiation stage between the pre-b-cell and the early b lymphocyte .
