Abstract Optimization of therapy for childhood acute lymphoblastic leukemia (ALL) requires a greater understanding of the cells that proliferate to maintain this malignancy because a significant number of cases relapse, resulting from failure to eradicate the disease. Putative ALL stem cells may be resistant to therapy and subsequent relapses may arise from these cells. We investigated expression of CD133, CD19, and CD38 in pediatric B-ALL. Cytogenetic and molecular analyses demonstrated that karyotypically aberrant cells were present in both CD133+/CD19+ and CD133+/CD19− subfractions, as were most of the antigen receptor gene rearrangements. However, ALL cells capable of long-term proliferation in vitro and in vivo were derived from the CD133+/CD19− subfraction. Moreover, these CD133+/CD19− cells could self-renew to engraft serial nonobese diabetic–severe combined immunodeficient recipients and differentiate in vivo to produce leukemias with similar immunophenotypes and karyotypes to the diagnostic samples. Furthermore, these CD133+/CD19− ALL cells were more resistant to treatment with dexamethasone and vincristine, key components in childhood ALL therapy, than the bulk leukemia population. Similar results were obtained using cells sorted for CD133 and CD38, with only the CD133+/CD38− subfraction demonstrating xenograft repopulating capacity. These data suggest that leukemia-initiating cells in childhood B-ALL have a primitive CD133+/CD19− and CD38− phenotype.

Abstract Only some acute lymphoblastic leukemia (ALL) cells are thought to be capable of proliferating to maintain the leukemic clone, and these cells may be the most relevant to target with treatment regimens. We have developed a serum-free suspension culture (SC) system that supported growth of B-ALL cells from 33 patients for up to 6 weeks. ALL cells from 28 cases (85%) were expanded in this system, and growth was superior in SC than in long-term bone marrow culture. To characterize ALL progenitors, cells were sorted for expression of CD34 and CD10 or CD19 and the subfractions assayed in SC and in nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice. Cells capable of long-term proliferation in vitro and NOD/SCID repopulation were derived only from the CD34+/CD10- and CD34+/CD19- subfractions, and these cells could engraft secondary recipients. The engrafted cells had the same immunophenotype and karyotype as was seen at diagnosis, suggesting they had differentiated in vivo. These results demonstrate that ALL cells capable of long-term proliferation in vitro and in vivo are CD34+/CD10-/CD19-. This suggests that cells with a more immature phenotype, rather than committed B-lymphoid cells, may be the targets for transformation in B-ALL.

Abstract Continuous xenografts from 10 children with acute lymphoblastic leukemia (ALL) were established in nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice. Relative to primary engrafted cells, negligible changes in growth rates and immunophenotype were observed at second and third passage. Analysis of clonal antigen receptor gene rearrangements in 2 xenografts from patients at diagnosis showed that the pattern of clonal variation observed following tertiary transplantation in mice exactly reflected that in bone marrow samples at the time of clinical relapse. Patients experienced diverse treatment outcomes, including 5 who died of disease (median, 13 months; range, 11-76 months, from date of diagnosis), and 5 who remain alive (median, 103 months; range, 56-131 months, following diagnosis). When stratified according to patient outcome, the in vivo sensitivity of xenografts to vincristine and dexamethasone, but not methotrexate, differed significantly (P = .028, P = .029, and P = .56, respectively). The in vitro sensitivity of xenografts to dexamethasone, but not vincristine, correlated significantly with in vivo responses and patient outcome. This study shows, for the first time, that the biologic and genetic characteristics, and patterns of chemosensitivity, of childhood ALL xenografts accurately reflect the clinical disease. As such, they provide powerful experimental models to prioritize new therapeutic strategies for future clinical trials.

Abstract This article describes the course of a patient who received an allogeneic marrow graft from his HLA-identical sister for acute lymphoblastic leukemia in second remission. In the second month after grafting, marrow aspirates showed the presence of 7%-10% lymphoblasts. In addition, cytogenetic examination indicated the persistence of host cells. Thereafter, the patient had morphologically normal marrow examinations, with no evidence for recurrent leukemia. In addition, stable hematopoietic chimerism in both the lymphoid and myeloid cell lines has persisted for over 5 yr. Between 20% and 50% of phytohemagglutinin-stimulated peripheral blood mononuclear cells were host-derived on repeated studies. A marrow sample 4 yr after transplantation was established in long-term culture and produced 2% host granulocyte-macrophage colonies at its inception, but 24% host colonies by week 4. Despite this persistent chimerism, no in vitro or in vivo abnormalities of hematopoiesis have been detected.

Acute myeloid leukemia (AML) occurs as the result of malignant transformation in a hematopoietic progenitor cell, which proliferates to form an accumulation of AML blasts. Only a minority of these AML cells are capable of proliferation in vitro, suggesting that AML cells may be organized in a hierarchy, with only the most primitive of these cells capable of maintaining the leukemic clone. To further investigate this hypothesis, we have evaluated a strategy for purifying these primitive cells based on surface antigen expression. As an in vitro endpoint, we have determined the phenotype of AML progenitor cells which are capable of producing AML colony-forming cells (CFU) for up to 8 weeks in suspension culture (SC) and compared the phenotype with that of cells which reproduce AML in nonobese diabetic/severe combined immunodeficiency (NOD/SCID) mice. AML cells were fluorescence-activated cell sorted (FACS) for coexpression of CD34 and CD71, CD38, and/or HLA-DR and the subfractions were assayed in vitro and in vivo at various cell doses to estimate purification. While the majority of primary AML CFU lacked expression of CD34, most cells capable of producing CFU after 2 to 8 weeks in SC were CD34+/CD71−. HLA-DR expression was heterogeneous on cells producing CFU after 2 to 4 weeks. However, after 6 to 8 weeks in SC, the majority of CFU were derived from CD34+/HLA-DR− cells. Similarly, the majority of cells capable of long-term CFU production from SC were CD34+/CD38−. Most cells that were capable of engrafting NOD/SCID mice were also CD34+/CD71− and CD34+/HLA-DR−. Engraftment was not achieved with CD34+/CD71+ or HLA-DR+subfractions, however, in two patients, both the CD34+and CD34− subfractions were capable of engrafting the NOD/SCID mice. A three-color sorting strategy combining these antigens allowed approximately a 2-log purification of these NOD/SCID leukemia initiating cells, with engraftment achieved using as few as 400 cells in one experiment. Phenotyping studies suggest even higher purification could be achieved by combining lack of CD38 expression with the CD34+/CD71− or CD34+/HLA DR− phenotype. These results suggest that most AML cells capable of long-term proliferation in vitro and in vivo share the CD34+/CD71−/HLA-DR− phenotype with normal stem cells. Our data suggests that in this group of patients the leukemic transformation has occurred in a primitive progenitor, as defined by phenotype, with some degree of subsequent differentiation as defined by functional assays.

Abstract Introduction: Transforming events in B-lineage (ALL) occur primarily at the level of committed progenitor cells, but the phenotype, frequency and hierarchical organization of leukemia-initiating cells (LICs) are controversial. Pronounced clonal heterogeneity in ALL and the lack of preclinical models impede functional analysis of LICs and dissecting the clonal architecture of B-cell precursor acute lymphoblastic leukemia (BCP-ALL). Aims and methods: To identify cellular features associated with cell fate and decisions, engraftment potential, growth kinetics and resistance to therapy of BCP-ALL LICs at the clonal level, we generated multiple single-cell-derived clones from patient derived-long-term cultures (PD-LTCs) of human BCP-ALL. This in vitro ALL-LTC model allows prolonged serum-, cytokine-, and stroma-free culture of patient-derived BCP-ALL cells that are largely stable in terms of cytogenetic and immunophenotypic features for up to 6 months [Nijmeijer B et. al, Exp Hematol. 2009;37:376; Badura S et al., PLoS One. 2013; 8:e80070] Three ALL-LTCs were selected on the basis of different patterns of surface marker expression and cytogenetics, i.e. Ph+ ALL (LTCs PH and BV; common-ALL) and BCR-ABL negative ALL (LTC CR; pre B-ALL), respectively. Results: Clonogenic growth in semisolid medium ranged from 0.25% to 8% for these ALL-LTCs (CR 8%, PH 0.45% and BV 0.25%), consistent with functional diversity within the bulk as well as the immunophenotypically defined subsets. To analyze these subpopulations at the clonal level, we isolated leukemic cell subsets by cell sorting on the basis of CD20, CD34 and CD38 expression, and then generated hundreds of clones by expanding single-cell sorted subpopulations. All sorted cell fractions from all three ALL-LTCs were capable of initiating long-term growth in vitro. In limiting dilution cultures, 1% to 5% of single sorted cells derived from these cell fractions gave rise to prolonged leukemic cell growth. To evaluate the leukemia-initiating capacity of the clonal ALL subpopulations in vivo, we examined engraftment and outgrowth kinetics of different ALL clones in a xenograft model with sublethally irradiated NSG mice. Individual clones derived from different sorted subpopulations displayed pronounced differences in engraftment potential and aggressiveness based on analyses of blood, bone marrow and spleen. This ranged from rapid appearance of ALL and death within 70-80 days (clone PH 20), to complete lack of leukemic outgrowth 155 days after transplantation (clone PH clone 14). The other four clones derived from this ALL (PH) displayed intermediate engraftment and outgrowth kinetics. Notably, leukemogenic properties were not associated with a distinct surface marker profile based in CD20, CD34 and CD38 expression. A similar heterogeneity of leukemogenic potential was determined with clonal subpopulations from the LTC BV. To assess the hierarchical relationship between different clones and the association with LIC capacity, we examined the pattern of immunoglobulin VDJ-rearrangement of different clones. The Ig rearrangement patterns confirm that the clones represent distinct clonal populations derived from the original polyclonal LTC, but we observed no hierarchical relationship with respect to the biological properties of different clones. Further functional evaluation of these subclones was performed by videomicroscopy-based single cell tracking that allows analysis of individual cells and their progeny over many cell divisions. We observed concordance between cell cycle length and cell death events as determined by single cell tracking and the engraftment potential and aggressiveness of LTCs derived single cell clones in vivo. To elucidate the molecular basis for the biologic differences between the clonal ALL populations, we compared highly and poorly leukemogenic clones by SILAC based proteomics. Only 5% of 6500 proteins measured in clones differing in their leukemia-initiating potential were differentially regulated, and these proteins could be assigned to a limited number of pathways. In conclusion, comparative evaluation of clonal lymphoblast populations generated from patient-derived ALL long-term cultures by combined in vitro analysis, single cell videomicroscopy, xenotransplantation and proteomics is a promising approach to identify specific markers and therapeutic strategies that target LIC in ALL.

Abstract The Fas receptor and its ligand have been implicated in mediating the bone marrow (BM) suppression observed in graft-versus-host disease and a number of other BM-failure syndromes. However, previous studies have suggested that Fas is probably not expressed on human hematopoietic stem cells (HSCs), but up-regulated as a consequence of their commitment and differentiation, suggesting that progenitors or differentiated blood cells, rather than HSCs, are the targets of Fas-mediated suppression. The present studies confirm that candidate HSCs in human cord blood and BM lack constitutive expression of Fas, but demonstrate that Fas expression on CD34+ progenitor and stem cells is correlated to their cell cycle and activation status. With the use of recently developed in vitro conditions promoting HSC self-renewing divisions, Fas was up-regulated on virtually all HSCs capable of multilineage reconstituting nonobese diabetic/severe combined immunodeficiency (NOD-SCID) mice in vivo, as well as on long-term culture-initiating cells (LTC-ICs). Similarly, in vivo cycling of NOD-SCID repopulating cells upon transplantation, resulted in up-regulation of Fas expression. However, repopulating HSCs expressing high levels of Fas remained highly resistant to Fas-mediated suppression, and HSC function was compromised only upon coactivation with tumor necrosis factor. Thus, reconstituting human HSCs up-regulate Fas expression upon active cycling, demonstrating that HSCs could be targets for Fas-mediated BM suppression. (Blood. 2003;102: 118-126)

Abstract Acute myeloid leukaemia (AML) is thought to be maintained by a small population of leukemic progenitor cells. To define the phenotype of such cells with long-term proliferative capacity in vitro and in vivo, we have used the production of leukemic clonogenic cells (CFU) after 2 to 8 weeks in suspension culture as a measure of these cells in vitro and compared their phenotype with that of cells capable of engrafting nonobese diabetic severe combined immune deficient (NOD/SCID) mice. Leukemic blast peripheral blood cells were evaluated for expression of CD34 and Thy-1 (CD90) antigens. The majority of AML blast cells at diagnosis lacked expression of Thy-1. Most primary CFU-blast and the CFU detected at up to 8 weeks from suspension cultures were CD34+/Thy-1−. AML cells that were capable of engrafting NOD/SCID mice were also found to have the CD34+/Thy-1− phenotype. However, significant engraftment was achieved using both CD34+/Thy-1− and CD34− subfractions from one AML M5 patient. These results suggest that while heterogeneity exists between individual patients, the leukemic progenitor cells that are capable of maintaining the disease in vitro and in vivo differ from normal hematopoietic progenitor cells in their lack of expression of Thy-1.
