Abstract
A lineage switch in leukemia, in which the leukemic cell lineage at onset converts to another lineage at a later time, is an uncommon type of hybrid (mixed) leukemia regarded as a variation of bilineage leukemia. We present a case of a 60-year-old female diagnosed with precursor B cell acute lymphoblastic leukemia (ALL), whose markers in flow cytometry shifted from their original status of CD19+, 22+, 79a+, 13+, HLA-DR+, and TdT+. Although her bone marrow achieved remission after induction therapy, there was a small residual population of leukemic cells in the liver. Residual disease was proved by biopsy and pathologically shown to have an immature phenotype of CD5+, CD10-, CD20-, CD79a- and myeloperoxidase negativity. Two weeks after liver biopsy, blast cells progressively appeared in the peripheral blood; these cells had a monocytoid morphology and phenotype (CD13, 14) but were accompanied by myeloid (CD33) and lymphoid (CD2, 4, 20) cells. Markers CD7, 10 and 19 were negative by flow cytometry. This phenotypical conversion from B-ALL to hybrid leukemia featuring monocytoid characteristics is known as a lineage switch. This case suggests that leukemic subclones tend to carry out dedifferentiation, occasionally in extramedullary sites, which serve as a hotbed for the selection of resistant clones.

Abstract
E2a/Pbx1 is a fusion oncoprotein resulting from the t(1;19) translocation found in human pre-B acute lymphocytic leukemia and in a small number of acute T-lymphoid and myeloid leukemias. It was previously suggested that E2a/Pbx1 could cooperate with normal or oncogenic signaling pathways to immortalize myeloid and lymphoid progenitor cells. To address this question, we introduced the receptor of the macrophage-colony-stimulating factor (M-CSF-R) in pro-T cells immortalized by a conditional, estradiol-dependent, E2a/Pbx1-protein, and continuously proliferating in response to stem cell factor and interleukin-7. We asked whether M-CSF-R would be functional in an early T progenitor cell and influence the fate of E2a/Pbx1-immortalized cells. E2a-Pbx1 immortalized pro-T cells could proliferate and shifted from lymphoid to myeloid lineage after signaling through exogenously expressed M-CSF-R, irrespective of the presence of estradiol. However, terminal macrophage differentiation of the cells was obtained only when estradiol was withdrawn from cultures. This demonstrated that M-CSF-R is functional for proliferation and differentiation signaling in a T-lymphoid progenitor cell, which, in addition, unveiled myeloid potential of pro-T progenitors. Moreover, the block of differentiation induced by the E2a/Pbx1 oncogene could be modulated by hematopoietic cytokines such as M-CSF, suggesting plasticity of leukemic progenitor cells. Finally, additional experiments suggested that PU.1 and eight twenty-one transcriptional regulators might be implicated in the mechanisms of oncogenesis by E2a/Pbx1.

Abstract
We evaluated the effects of ectopic granulocyte/macrophage colony-stimulating factor (GM-CSF) signals on hematopoietic commitment and differentiation. Lineage-restricted progenitors purified from mice with the ubiquitous transgenic human GM-CSF receptor (hGM-CSFR) were used for the analysis. In cultures with hGM-CSF alone, hGM-CSFR-expressing (hGM-CSFR+) granulocyte/monocyte progenitors (GMPs) and megakaryocyte/erythrocyte progenitors (MEPs) exclusively gave rise to granulocyte/monocyte (GM) and megakaryocyte/erythroid (MegE) colonies, respectively, providing formal proof that GM-CSF signals support the GM and MegE lineage differentiation without affecting the physiological myeloid fate. hGM-CSFR transgenic mice were crossed with mice deficient in interleukin (IL)-7, an essential cytokine for T and B cell development. Administration of hGM-CSF in these mice could not restore T or B lymphopoiesis, indicating that enforced GM-CSF signals cannot substitute for IL-7 to promote lymphopoiesis. Strikingly, >50% hGM-CSFR+ common lymphoid progenitors (CLPs) and >20% hGM-CSFR+ pro-T cells gave rise to granulocyte, monocyte, and/or myeloid dendritic cells, but not MegE lineage cells in the presence of hGM-CSF. Injection of hGM-CSF into mice transplanted with hGM-CSFR+ CLPs blocked their lymphoid differentiation, but induced development of GM cells in vivo. Thus, hGM-CSF transduces permissive signals for myeloerythroid differentiation, whereas it transmits potent instructive signals for the GM differentiation to CLPs and early T cell progenitors. These data suggest that a majority of CLPs and a fraction of pro-T cells possess plasticity for myelomonocytic differentiation that can be activated by ectopic GM-CSF signals, supporting the hypothesis that the down-regulation of GM-CSFR is a critical event in producing cells with a lymphoid-restricted lineage potential.

Abstract
Cells coexpressing lymphoid and myeloid cell surface markers have been described for various leukemias and non-Hodgkin's lymphomas. It is unclear whether these mixed lineage characteristics are due to malignancies of early progenitor cells or alternatively to malignant cells with lineage infidelity. Recently, it has been shown that cells coexpressing lymphoid and myeloid markers can be generated from peripheral blood lymphocytes from normal individuals as well. In this review, consequences of this surprising fact are discussed.

Abstract
Granule protein deficiencies in morphologically mature neutrophil cells of peripheral blood from human patients with acute myeloid leukemia was demonstrated using post-embedding immunocytochemistry. Abnormal immunoreactivity of granule proteins was detected in seven of nine patients. Decreased immunoreactivity patterns were found more for the primary granule markers elastase and myeloperoxidase than for the secondary granule marker lactoferrin. Leukemias with a predominant myeloid component, in contrast to those with a predominant monocytoid component, had more neutrophil cells showing immunodeficiencies for one or more granule markers. The proportion of neutrophil cells showing immunodeficiencies varied greatly for each granule marker; more variation was obtained for elastase, lactoferrin and myeloperoxidase than for lysozyme, possibly because lysozyme is a marker for both granule types. In addition, no correlation could be found between any of the immunoreactivity deficiencies for the neutrophil granule glycoproteins elastase, lactoferrin, lysozyme and myeloperoxidase and the abundance of a particular set of ultrastructural features in the circulating leukemic cells from any of the nine patients. Nonetheless, most of the immature myeloid cells from peripheral blood of leukemic patients showing neutrophil protein immunoreactivity abnormalities in one or more granule markers often and randomly displayed one or more unusual ultrastructural features. The clinical and pathological significance of neutrophil granule protein deficiencies and the abundance of fibrillar structures in malignant myeloid cells presently is uncertain.

Abstract
Morphological, immunological and cytogenetic features were studied in 27 adults presenting with Ph chromosome-positive acute lymphoblastic leukaemia (ALL), in correlation with clinical outcome. Twenty patients (group 1) were diagnosed as having typical ALL according to the FAB criteria supported by immunological findings. Less than 1% blast cells with azurophilic granules were detected in all cases. Myeloid cytochemistry, i.e. peroxidase and Sudan black-B stain, was negative in all cases. A minor phenotype deviation consisting of the expression of the CD13 myeloid-associated marker was detected in two patients. In seven patients (group 2) a diagnosis of ALL with a minor myeloid component was made because of the presence of a majority of lymphoid blasts and of 5-15% blast cells with morphological cytochemical and immunological features of the myeloid lineage. Abnormal metaphases were found in 6/20 (30%) patients in group 1, compared with 7/7 (100%) patients in group 2. All patients were treated by antilymphoid regimens; however, complete remission was achieved in 17/20 (85%) patients in group 1 versus 1/7 (14.3%) patients in group 2. Median survival was 16 months, range < 1-120+ in group 1 and 9 months, range < 1-15 in group 2. It is concluded that morphological, immunological and cytogenetic studies allow for the recognition of two cytological subsets of Ph+ ALL. The presence of a minor myeloid component in otherwise typical Ph chromosome-positive ALL may be associated with a distinct cytogenetic pattern and poor responses to antilymphoid therapy.

Abstract
The lineage affinity of 61 cases of acute unclassified leukemias (AUL) was reevaluated by ultrastructural analysis of peroxidase expression (POEM) in combination with immunophenotyping. In 24 cases a significant proportion of the blasts displayed ultrastructural myeloperoxidase (UMPO) and in another 3 cases platelet peroxidase (UPPO) suggesting the allocation of these leukemias to the myeloid or megakaryoblastic lineage. No significant correlation between myeloid surface marker expression and POEM positivity could be detected, while the presence of the CD 19 or CD 24 antigen significantly correlated with POEM negativity. The detection of lymphoid markers on POEM+ blasts indicates, that these leukemias might be derived from bipotential progenitors, which have retained their lymphoid antigens during myeloid differentiation. In one case a bilineage leukemia with a POEM+/CD 19- and a POEM-/CD 19+ population could be identified by immunoelectron microscopical studies (IEM). The remaining 34 AUL cases were POEM negative. Combined data suggest that these cases probably derive from early lymphoid progenitors. Taken together, AUL are heterogenous in presentation and in their cellular origin including a major portion of cases with an unequivocal myeloid differentiation detectable by ultrastructural analysis of myeloperoxidase expression.

Abstract
Conflicting results have been reported in recent years concerning the incidence and prognostic relevance of acute mixed-lineage leukemias (AMLL). Among the high number of possible hybrid antigen combinations, it is important to discriminate those occurring with sufficient frequency to be of general clinical significance. In this review an approach to a classification based upon the hierarchical import of developmental antigens seen during hemopoietic differentiation is suggested. As far as the clinical relevance of AMLL is concerned, some hybrid patterns have been found to be associated with distinct characteristics in terms of clinical features at the time of presentation and poor response to treatment. For these particular types of leukemia, the time has probably arrived to design more specific therapeutic regimens.

Abstract
We examined myeloid characteristics of myeloid-antigen-positive (My+) and -negative (My-) B-precursor acute lymphoblastic leukemia (ALL) blast cells. Immunophenotyping before and after culture, rearrangements of immunoglobulin heavy chain (IgH) and T-cell receptor (TCR) genes, stimulation of DNA synthesis with granulocyte colony-stimulating factor (G-CSF), and G-CSF binding assay were performed. Of My+ ALL blasts, the immunophenotypic staging as B-precursor ALL and rearrangements of IgH and TCR-beta, gamma and delta genes did not differ from findings in My- ALL blasts. Stimulated with G-CSF, cells from one My+ ALL and from one My- ALL patients showed enhancement of DNA synthesis and expression of CD11b and CD13, respectively. G-CSF binding was observed in blasts from 3 My+ ALL patients and one My- ALL child. After culture, blasts from My- ALL children expressed CD13 but showed neither enhanced DNA synthesis with G-CSF nor G-CSF binding. Thus, it would appear that (i) My+ and My- adult ALL blasts are at the same stage of differentiation; (ii) some My+ adult ALL blasts have phenotypic and functional myeloid characteristics; and (iii) induction of CD13 expression in My- ALL after in vitro culture does not correlate with other myeloid characteristics.

Abstract
Cytogenetic patterns in correlation with cytologic, biomolecular and clinical findings were studied in 45 adult patients with AML expressing at least one of the following lymphoid associated markers (LM): CD2, CD7, CD10, CD19, CD22, TdT. Four cytogenetic groups were recognized: group I, including 8 patients with 11q23 rearrangements; group II including 5 patients with the Ph chromosome; group III, with 19 patients and aberrations of the "myeloid type" including 4 cases with aberrations of chromosome 13, 3 cases with 1q and 7q anomalies, 2 cases with trisomy 11q; group IV, including 13 patients with normal karyotype. Patients showing extensive lineage infidelity were encountered more frequently in cytogenetic groups I and II than in groups III and IV. Two of 4 cases with aberrations of chromosome 13 showed two or more lymphoid features either at immunophenotyping or at biomolecular analysis of the configuration of lg and TCR genes. Patients with 11q23 rearrangements and with the Ph chromosome were generally young, presented with high WBC count and had low complete remission rate. Survival in Ph chromosome positive patients was uniformly short. We conclude that, although there is no cytogenetic anomaly specific for AML with LM, chromosome findings may be clinically relevant in AML with LM. A morphologic, immunologic and cytogenetic classification of AML with LM may constitute a working basis for future studies aimed at a better definition of clinicopathological features and optimal treatment strategy for these leukemias.

Abstract
In the light of recent observations reporting that B-lymphocytic leukemia (B-CLL) cells may express a variety of myelomonocytic antigens, 28 patients with B-CLL and B-leukemic lymphocytic lymphoma were studied for the presence of these antigens using monoclonal antibodies to detect CD13, CD33, CD15 and CD14. Analysis of immunofluorescence (IF) was carried out by two procedures; one which employed the standard conventional method of gating used in our laboratory for flow cytometry, while the other procedure increased the sensitivity of the analysis, by moving the marker for IF to the left, so as to widen the gate to include more cells with low IF. Using the conventional methodology, the mean proportion of cells considered positive was less than 3% for any of the 4 markers studied. In only a few patients were 5% or more of the B-CLL cells positive for some of the markers studied (3 patients with 6.2-11.3% CD13+; 2 with 6.0-9.6% CD14+, and one with 11.8% CD15+ cells). No case had more than 2.5% + CD33+ cells. The second procedure with a wider gate to enhance sensitivity for less positive cells, increased the number of positive cells for any of the markers in only 4 patients. These results are contradictory to others reported recently, and some of the possible causes for this discrepancy are discussed. It is suggested that more useful data may be obtained if the level of staining intensity and patterns of positive staining are documented in the future.

Abstract
The most recent sophisticated investigations have provided new and revealing, but also contradictory and controversial information on the biological nature and the cellular origin of Hodgkin and Reed-Sternberg cells (H-RS). Immunophenotypic analyses have shown variable phenotypic antigen expression; but, on balance the data suggest a lymphoid cell expressing T- and/or B-cell-associated markers and certain activation antigens while lacking immunological features of monocytes-macrophages or other lineages. Molecular genetic studies have demonstrated heterogenous findings with respect to rearrangements of T-cell receptor and immunoglobulin genes. Only a small percentage of the cases has rearrangements; this might be due to the threshold of sensitivity of the method combined with the scarcity of the malignant cells. Epstein-Barr virus (EBV) genomes are clonally integrated in the H-RS cells of about half the cases. The significance of these findings--whether EBV is a causative agent or an epiphenomenon--remains to be elucidated. H-RS cells express mRNA and proteins of various cytokines and cytokine receptors implying a predominant role for cytokines in the pathophysiology of HD. The mononuclear and polynuclear H-RS cells are capable of DNA synthesis and nuclear division; the lack of cellular division leads to multinuclearity through the process of endomitosis. Mutations and expression of only a limited number of oncogenes have been tested thus far. Whether the bcl-2 oncogene is involved in HD remains a matter of debate. Aneuploidy and non-random chromosomal abnormalities are the results of cytogenetic analyses of H-RS cells. However, no chromosomal marker specific for HD has yet been found. Thus, while studies of EBV involvement, growth factor production, oncogene expression and chromosomal abnormalities contributed a fair amount of new data on the nature of H-RS cells, only immunophenotyping and genotyping provided some indication of the cellular derivation: an activated lymphoid cell that possibly expresses oncogenes, that probably is infected with EBV, that most likely produces cytokines, that certainly has multiple karyotypic abnormalities.

Abstract
Minimal requirements and their rationale for the diagnosis and the response to treatment in childhood acute lymphoblastic leukemia (ALL) were defined in the recently instituted "BFM-Family"-Group, in which the German, Austrian, Dutch, Italian, Belgian, French and Hungarian childhood leukemia study groups cooperate. ALL is defined as > or = 25% lymphoblasts in the bone marrow; for confirmation of the diagnosis and classification the criteria of the French-American-British (FAB) criteria are retained. For determination of the extent of the disease at diagnosis or relapse the criteria by the Rome Workshop [1986] are recommended: An obligatory panel of monoclonal antibodies for immunophenotyping was defined, as well as criteria for precursor B-ALL and T-ALL. Cytogenetic studies may support the diagnosis and subtyping, and are essential to identify certain patients with a high risk of treatment failure (f.i. t(9;22), t(4;11)). The role of molecular genetics for the diagnosis and the characterization of leukemia and the value of its clinical application needs further elucidation. Relapse was defined as recurrence of evident leukemia in the blood, bone marrow (> or = 25% lymphoblasts) or at any other site (to be confirmed by histological examination). Bone marrow involvement combined with extramedullary relapse was defined as > or = 5% lymphoblasts in the bone marrow.

Abstract
Leukemic cells from 51 pediatric patients (younger than 18 years) diagnosed with acute lymphoid leukemia by standard morphologic and cytochemical methods were subjected to flow cytometric studies using a panel of monoclonal antibodies against T-cell (CD1, 2, 3, 4, 5, 7, 8), B-cell (CD10, 19, 20, 21), myeloid (CD13, 14, 15, 33), and HLA-DR antigens. Cases of "conventional" acute lymphoid leukemia (leukemic cells with a normal configuration of B-cell or T-cell differentiation antigens) were observed in 26 of 51 (51%) cases, whereas cases of "aberrant" acute lymphoid leukemia (cells with abnormal patterns of B-cell or T-cell antigens or with concomitant myeloid antigens) were noticed in 25 (49%) cases. Myeloid antigen-positive acute lymphoid leukemia was observed in the leukemic cells of eight (16%) individuals. No significant differences were observed between conventional and aberrant ALL in the distribution of sex, age, leukocyte count, hemoglobin concentration, platelet count, blast count, French-American-British (FAB) type, lymphadenopathy, organomegaly, rate or duration of remission, or survival. When only myeloid antigen-positive cases were compared with myeloid antigen negative-cases, no significant correlations were observed except for duration of first remission (myeloid antigen positive, 26+ +/- 22 months; myeloid antigen negative, 40+ +/- 18 months; P less than 0.001), and duration of survival (myeloid antigen positive, 27+ +/- 24 months; myeloid antigen negative, 62+ +/- 17 months; P = 0.001). These data suggest that pediatric patients with ALL blasts possessing myeloid antigens may represent a high-risk group for length of remission and survival.

Abstract
We studied 43 consecutive cases of acute leukemia for evidence of hybrid leukemia including biphenotypic or bilineal involvement. Twenty-two were initially diagnosed as acute lymphoblastic leukemia (ALL) and 21 as acute myelogenous leukemia (AML). Techniques included morphology, cytochemistry, immune phenotyping and cytogenetics. Thirty-one cases seemed restricted to one lineage. Twelve cases showed involvement of both lymphoid and myeloid cells. Dual staining immune phenotyping showed coexpression of diverse lineage markers. These data indicate a considerable proportion of unselected cases of acute leukemia are hybrid leukemias. These data are consistent with the notion that transformation frequently occurs in a stem or progenitor cell.

Abstract
We have analysed the configuration of immunoassociated genes and the karyotypes of 30 patients with acute myelocytic leukemia (AML) and 10 with chronic myelocytic leukemia in blast crisis (CML-BC). In AML, the frequencies of T-cell receptor (TcR) beta, gamma, and delta chain and immunoglobulin heavy and light chain gene rearrangements were 4.2%, 19%, 8%, 10.7% and 10.5%, respectively. In CML-BC, they were 10%, 20%, 40%, 50% and 0%, respectively. Nine patients had abnormalities in chromosome 2, 7 or 14, upon which immunoassociated genes are located. There seems to be no apparent relationship between these chromosome abnormalities and gene rearrangements. In all patients but one (5/6), the delta rearrangement was accompanied by other immunoassociated gene rearrangements. Molecular size analysis revealed specific delta rearranged band(s) (19.5 kb-BamHI and/or 6.9 kb-EcoRI), as commonly detected in B-acute lymphocytic leukemia (ALL). All the patients with the delta rearranged band, however, had a germline configuration of J delta gene loci, suggesting a DD or V(D)D (probably V delta 2(D)D) pattern. This study also indicates that the delta rearrangement is specific in AML or CML-BC and distinct from that in early T leukemia/lymphoma.

Abstract
Immunohistochemical investigations were performed on decalcified, paraffin-embedded iliac crest trephine biopsy specimens from 30 cases of acute myeloid leukemia (AML, as defined by the FAB classification) with antibodies against B cells (L26, 4KB5, MB1, Ki-B3), T cells (UCHL1, MT1), myeloid/histiocytic cells (anti-neutrophil elastase, MAC387, anti-S-100 protein, anti-alpha 1-antichymotrypsin, DAKO-M1), natural killer/killer cells (anti-Leu-7), and megakaryocytes (anti-factor VIII-related antigen). (1) The blast cells of all the cases reacted with from at least two to at most eight different antibodies. Each antibody reacted with blast cells in a minimum of two (maximum 30) cases. (2) MT1, Ki-B3, anti-alpha 1-antichymotrypsin anti-neutrophil elastase, anti-S-100 protein, and MAC387 stained blast cells in more than 50% of the cases; MB1, L26, UCHL1, 4KB5, and DAKO-M1 in 20% to 50% of the cases; and anti-Leu-7 and anti-factor VIII-related antigen in less than 20% of the cases. (3) In the majority of cases many T lymphocytes, a small-to-moderate number of B lymphocytes, and a few Leu-7-positive lymphoid cells were intermingled with the blast cells. In some cases, especially where only a minor proportion of the blast cells was immunostained, it was nearly impossible to distinguish the lymphocytes of the tumor's stromal reaction from small blast cells. Thus, AML exhibits a heterogeneous immunophenotype in trephine biopsy specimens. Immunohistologic diagnosis of this disease in such specimens may be extremely difficult. Since staining of the blast cells with one or more of the antibodies generally used to define B cells, T cells, or their neoplastic derivatives is not uncommon, misinterpretation as non-Hodgkin's lymphoma of high-grade malignancy could easily occur. These findings also suggest that mixed-type (hybrid) acute leukemias with coexpression of myeloid and lymphoid cell markers could be more common than generally realized.

Abstract
We studied clinical and biological features of five cases of hybrid leukemia. Three of the five patients were classified as biphenotypic leukemia because of the coexpression of myeloid/B lymphoid markers in patients 1 (FAB M2) and 2 (FAB CMMoL) and myeloid/T lymphoid markers in patient 3 (FAB M4). Patient 4 was identified as bilineal-biphenotypic leukemia because acute myelogenous leukemia (AML) (FAB M4) and acute lymphoblastic leukemia (ALL) (FAB L1) coexisted and each population coexpressed myeloid and T lymphoid markers. Patient 5 was identified as bilineal leukemia due to the conversion from AML (FAB M1) to ALL (FAB L1) at an interval of 3 months. The Philadelphia (Ph1) chromosome was negative in all cases. A leukemic blast colony formation using cell line 5637 conditioned medium as a stimulator was obtained in all four patients examined. Three of the five patients had been suffering from so-called stem cell disorders such as aplastic anemia in patient 2, trilineage myelodysplasia in patient 4 and refractory anemia with excess of blasts in transformation in patient 5. The pre-existing impairment of pluripotent stem cell was probably the background of these hybrid leukemia. Hybrid leukemia appears to have an inferior prognosis: an AML-directed chemotherapy resulted in a low remission rate (2/5) with a short duration of relapse free survival (1/2) and an ALL-directed chemotherapy produced no remission (0/3). Chronological phenotypic analysis revealed that hybrid features of leukemic blasts disappeared at the time of relapse in patient 1 and progression to AML in patient 2. Monitoring of lineage-associated markers should be required for the management of hybrid leukemia.

Abstract
The immunophenotype of 135 previously untreated patients with FAB defined acute myeloid leukaemia (AML) was studied at diagnosis. The panel of reagents included monoclonal antibodies (MoAb) recognising myeloid-associated determinants (CD11, CD13, CD14, CD33 and others) as well as MoAb directed towards lymphoid antigens (CD7, CD10, CD19) and TdT. The results indicate that CD13 and/or CD33 are consistently expressed in AML and only rarely in ALL blasts (131/135 + ve cases, versus 4/130 in ALL). Lymphoid antigen expression was rarely detected when CD10 and CD19 were investigated in AML (0.9% and 2% + ve cases, respectively), whereas significant positivities were found for TdT and CD7 (20% and 10% respectively). Concerning FAB subtypes, two new MoAb (LAM3 and LAM7) proved very useful in the specific recognition of AML with monocytic features. The phenotype CD13+ and/or CD33+, CD9+, HLA-DR- was found to be almost exclusive for M3 AML. The response to induction chemotherapy was analysed in CD7+ and in TdT+ patients. In the latter group a statistically significant lower response rate was found with respect to TdT-ve-AML patients.

Abstract
ML cell lines (ML-1, -2, and -3) were derived from the cells of a patient with acute myelocytic leukemia preceded by a T-cell malignant lymphoma. A deletion of chromosome 11 (11q-) was common to the affected cells in both neoplastic phases. We report here that the three ML cell lines have DNA rearrangements of the T-cell receptor (TcR)-beta and gamma-chain genes in addition to immunoglobulin heavy-chain gene rearrangement, though they do not have TcR gene messages. The findings presented here indicate that ML cell lines could be used as models for the elucidation of the bilineal nature of hematopoietic neoplastic cells, though they have a biphenotypic (myelomonocytic/T-cell) marker expression.

Abstract
The configuration of the immunoglobulin heavy chain (IgH), T-cell receptor (TcR) beta and gamma chain regions, and the major breakpoint cluster region (M-bcr) genes were analysed in four cases of Ph' + acute leukemia (AL). Monoclonal rearrangements of the IgH region were detected in three cases exhibiting two phenotypically distinct cell populations (i.e. one lymphoid and one myeloid. In one of these cases, identical genetic events were observed by molecular analysis of FACS separated blasts. Multi-lineage rearrangements involving also the TcR gamma gene were observed in a biphenotypic AL showing co-expression of markers. The lack of rearrangements within the M-bcr gene, together with demonstration in one case of the Ph' + AL specific p190 protein product, pointed against the occurrence of chronic myeloid leukemias presenting in blastic transformation. Our results imply that such cases are to be considered as true AL and should therefore be included in the definition of hybrid AL.

Abstract
Recent progress in immunophenotyping includes the availability of monoclonal antibodies (MAbs), knowledge of specificity and reactivity patterns of these reagents, and the technical improvements and standardization of immunofluorescence and immunocytology staining procedures, including flow cytometry. These advances have contributed significantly to the establishment of immunophenotyping as an essential diagnostic tool in the differential diagnosis of types of acute leukaemia. Immunophenotyping allows for the objective and reproducible distinction of acute lymphoblastic leukaemia (ALL) from acute myeloblastic leukaemia (AML) and of T-lineage from B-lineage ALL. Immunologically defined ALL and AML subtypes have been found to convey prognostic significance. Using cell lineage-specific and differentiation stage-specific MAbs, cases of T- and B-lineage ALL and of AML can be further classified into a number of different subtypes. Routine immunophenotyping concentrates on the diagnostic enquiry into a few major, clinically relevant subtypes; only a limited number of crucial reagents are employed that are commercially available. The simplification and standardization of discriminatory immunomarker panels make immunophenotyping a reliable diagnostic instrument for the provision of critical data to make a differential diagnosis. An effort to identify the nature and origin of the blast cells precisely, immunological typing definitely plays an important part in the multiple-marker analysis of acute leukaemia (morphology, cytochemistry, karyotyping, genotyping) for applied diagnostic and fundamental research purposes.
