Infection with cytomegalovirus (CMV) continues to be one of the most common complications following allogeneic bone marrow transplantation. A proportion of patients with CMV infection also experience neutropenia. To investigate the possible role of CMV in the suppression of hematopoiesis, we have examined the effect of CMV on the growth of isolated myeloid progenitors and on the production of myeloid cells in the long-term bone marrow culture (LTMC) system. In these studies, various isolates of CMV were added either directly to cultures of progenitors or to LTMC established from normal CMV-seronegative donors. In the first system, myelosuppression is manifested by a reduction in the number of colonies that grow. In the second system, myelosuppression is manifested by a reduction in the number of myeloid cells produced and released into the culture supernatant. Analysis of the data observed indicated that myelosuppression could in some cases be attributed to direct infection of myeloid progenitors. In other cases stromal cells were infected. In the latter cases, myelosuppression was then caused by an alteration in cytokines produced by the stromal cells. These observations made in vitro raise the possibility that comparable mechanisms may be responsible for the myelosuppression observed with CMV infection in vivo. To pursue this possibility we proposed to detect the CMV genome in defined subpopulations of marrow cells isolated from infected patients. Given the technical restrictions imposed by the small sample size available from patient marrow aspirations, our initial attempts to develop on appropriate technique involved isolation of cells from CMV-seropositive normal bone marrow donors. Using the polymerase chain reaction we were able to amplify CMV DNA contained within marrow cells of some healthy CMV-seropositive marrow donors.
