Marrow cells and thymocytes of unprimed donor mice were transplanted separately into X-irradiated syngeneic hosts, with or without sheep erythrocytes (SRBC). Antigen-dependent changes in number or function of potentially immunocompetent cells were assessed by retransplantation of thymus-derived cells with fresh bone marrow cells and SRBC; of marrow-derived cells with fresh thymocytes and SRBC; and of thymus-derived with marrow-derived cells and SRBC. Plaque-forming cells (PFC) of the direct (IgM) and indirect (IgG) classes were enumerated in spleens of secondary host mice at the time of peak responses. By using this two-step design, it was shown (a) that thymus, but not bone marrow, contained antigen-reactive cells (ARC) capable of initiating the immune response to SRBC (first step), and (b) that the same antigen complex that activated thymic ARC was required for the subsequent interaction between thymus-derived and marrow cells and/or for PFC production (second step). Thymic ARC separated from marrow cells but exposed to SRBC proliferated and generated specific inducer cells. These were the cells that interacted with marrow precursors of PFC to form the elementary units for plaque responses to SRBC, i.e. the class- and specificity-restricted antigen-sensitive units. It was estimated that each ARC generated 80–800 inducer cells in 4 days by way of a minimum of 6–10 cell divisions. On the basis of the available evidence, a simple model was outlined for cellular events in the immune response to SRBC.

We have previously shown that old mice produce more hapten-augmentable plaque-forming cells (PFC) than do young animals, suggesting a greater auto-antiidiotype antibody (auto anti-Id) component in their immune response. In the present studies this is confirmed serologically. The marked auto-anti-Id response of aged mice can be transferred to lethally irradiated young recipients with spleen but not bone marrow cells from old donors, suggesting that it is an intrinsic property of their peripheral B cell population and that the distribution of Id arising from the bone marrow of old and young mice is similar. In contrast with young mice the auto-anti-Id response of old animals is relatively T cell-independent and old donors do not show an increase in their ability to transfer an auto-anti-Id response after priming with TNP-F. These observations suggest that old mice behave as if already primed for auto-anti-Id production. Irradiated mice reconstituted with bone marrow cells from either young or old donors together with splenic T cells from old donors generate a relatively large auto-anti-Id response, whereas mice reconstituted with bone marrow from either young or old donors together with splenic T cells from young donors produce few hapten-augmentable PFC. It is suggested that differences in Id expression and auto-anti-Id production are the consequences of the interaction of Id (and anti-Id) arising from the marrow with anti-Id (and Id) present in the peripheral T cell population which serves as a repository of information about shifts in Id distribution, resulting from lifelong interactions with environmental and self-antigens.

Abstract In the last years, focus of regenerational studies has pointed on mesenchymal stem cells (MSC) and their ability to differentiate into several mesenchymal tissues. MSC have been shown to play a pivotal role in the microenvironment of bone marrow cells and in the modulation of immune response as they can suppress lymphocytic proliferation in vitro. Moreover, some animal studies have suggested they could favor the proliferation of malignant cell clones in solid tumor models. Their role in hematological malignancies, however, remains to be further elucidated and little is known about the influence of MSC in the development and maintenance of the malignant clone in chronic myeloid leukemia (CML). This disease is characterized by the presence of the Philadelphia (Ph) chromosome, a fusion product generated by the reciprocal translocation between chromosomes 9 and 22. Previous reports showed that hepatocytes precursors, found in the liver of CML patients carry the Ph translocation. Our intent was to elucidate whether MSC isolated from patients with CML in different stages of the disease originate from the malignant clone. To this purpose bone marrow aspirates of 11 patients with CML were obtained after informed consent. Five patients were analyzed at diagnosis, two after allogenic stem cell transplantation, three on treatment with the tyrosine kinase inhibitor imatinib and one on treatment with interferon alpha in combination with hydroxyurea. MSC were then generated as previously described. Briefly, cells were isolated by density gradient methods, resuspended in RPMI1640 medium containing 10% fetal bovine serum and plated in culture flasks to adhere. After 4–5 weeks of culture cells were collected and characterized by the expression of several surface markers in a fluorescence activated cell sorter (FACS). The presence of the Ph chromosome was assessed by both fluorescence in situ hybridization (FISH) and polymerase chain reaction (nested PCR). Moreover whole bone marrow was analyzed and results compared with those obtained in the MSC population. MSC showed a typical morphological pattern, growing to confluence after a few weeks of culture and appearing as an adherent, spindle shaped cell layer. In FACS they stained positive for SH2 and SH3 and did not express CD34, CD45 and CD14. MSC were then analyzed by FISH using probes for BCR-ABL. We could not detect the Ph translocation in any of the analyzed patients, though it was present at variuos levels in the remnant bone marrow cells. Results did not change, if expression of BCR-ABL was measured by high sensitivity RT-PCR. Our results showh that MSC of patients with CML are Philadelphia negative irrespective of the stage of disease and the treatment given, suggesting that these cells are not involved in the development of the malignancy. However, their interactions with leukemic cells as well as their role in the immune response against the tumor remains to be further characterized.

The cellular basis of the genetic control of the immune response to poly(LTyr, LGlu)-polyDLAla--polyLLys [(T,G)-A--L] in SJL (H-2s, low responder) mice has been investigated using T-cell factors. Thymocytes of SJL origin were educated to (T,G)-A--L and tested for their ability to produce an antigen-specific factor capable of cooperating in vivo with bone marrow cells of either SJL or C3H.SW (high responder) origin. SJL T cells were found to be incapable of producing such a cooperative factor, in contrast with results previously obtained with C3H/HeJ (low responders) and C3H.SW strains. Moreover, SJL bone marrow cells did not produce an antibody response to (T,G)-A--L, even when combined with factor produced by high responder (C3H.SW) mice. Thus, both T and B cells appear to be defective in the SJL strain in the response to (T,G)-A--L.

Two new methods are described for making chromosomal spreads of single antibody-forming cells. The first depends on the controlled rupture of cells in small microdroplets through the use of a mild detergent and application of a mechanical stress on the cell. The second is a microadaptation of the conventional Ford technique. Both methods have a success rate of over 50%, though the quality of chromosomal spreads obtained is generally not as good as with conventional methods. These techniques have been applied to an analysis of cell to cell interaction in adoptive immune responses, using the full syngeneic transfer system provided by the use of CBA and CBA/T6T6 donor-recipient combinations. When neonatally thymectomized mice were restored to adequate immune responsiveness to sheep erythrocytes by injections of either thymus cells or thoracic duct lymphocytes, it was shown that all the actual dividing antibody-forming cells were not of donor but of host origin. When lethally irradiated mice were injected with chromosomally marked but syngeneic mixtures of thymus and bone marrow cells, a rather feeble adoptive immune response ensued; all the antibody-forming cells identified were of bone marrow origin. When mixtures of bone marrow cells and thoracic duct lymphocytes were used, immune restoration was much more effective, and over three-quarters of the antibody-forming mitotic figures carried the bone marrow donor chromosomal marker. The results were deemed to be consistent with the conclusions derived in the previous paper of this series, namely that thymus contains some, but a small number only of antigen-reactive cells (ARC), bone marrow contains antibody-forming cell precursors (AFCP) but no ARC, and thoracic duct lymph contains both ARC and AFCP with a probable predominance of the former. A vigorous immune response to sheep erythrocytes probably requires a collaboration between the two cell lineages, involving proliferation first of the ARC and then of the AFCP. The results stressed that the use of large numbers of pure thoracic duct lymphocytes in adoptive transfer work could lead to good adoptive immune responses, but that such results should not be construed as evidence against cell collaboration hypotheses. Some possible further uses of single cell chromosome techniques were briefly discussed.
