A series of monoclonal antibodies reactive with normal myeloid cells at different stages of differentiation (anti-MY4, -MY7, -MY8, -Mo1, -Ia) were used to characterize the leukemic cells of 70 patients with acute myeloblastic leukemia (AML). Sixty-two of the leukemias expressed a phenotype corresponding to a recognizable immature normal myeloid cell. These(More)
A monoclonal antibody, anti-N901, was produced by fusing NS-1 myeloma cells with spleen cells of a mouse immunized with human CML cells. This antibody was reactive with a subpopulation of peripheral blood LGL, including the natural killer cells. Monocytes, granulocytes, B cells, T cells (T3+ cells), erythrocytes, and platelets were nonreactive. The(More)
The surface antigen phenotype of 30 patients with the blast phase of chronic myeloid leukemia (CML) was determined using a panel of monoclonal antibodies recognizing differentiation antigens of normal myeloid, erythroid, megakaryocyte, and lymphoid cells. Ten patients' cells expressed a phenotype corresponding to an immature myeloid cell and were felt to(More)
Bone marrow transplantation (BMT) is a unique cancer therapy characterized by its novelty, intensity, and toxicity. Although families have been identified as having a critical influence on patient adaptation during the acute phase of BMT, minimal attention has been paid to their experiences during extended survivorship. This article reviews findings from a(More)
A murine monoclonal antibody (anti-MY7) has been developed that detects an antigen expressed by 6% of normal human bone marrow cells, including approximately 40% of myeloid colony-forming cells (CFU-C). The number of bone marrow cells and CFU-C expressing MY7 is significantly increased in regenerating bone marrow, but less than 5% of peripheral blood CFU-C(More)
There is little evidence to suggest that T lymphocytes are involved in the leukemic process in chronic myeloid leukemia (CML). A case of CML in blast phase is described in which T-cell surface antigens were detected by immunofluorescence on the patient's blasts using monoclonal antibodies. In order to determine that the T-cell blasts were derived from the(More)
We have developed a ball-tipped catheter with a retractable 22-gauge, 7-mm long needle to perform endoscopic needle aspiration (ENA) for cytology and compared this technique to brush cytology of malignant-appearing biliary strictures during ERCP. Of 31 patients, 26 had proven malignant strictures involving the common bile duct and 5 had benign lesions. All(More)
The proliferation and differentiation of granulocyte and monocyte progenitor cells (CFU-C) in vitro is dependent on the presence of a group of closely related glycoproteins termed colony-stimulating factors (CSF). In order to investigate the interaction of these factors with CFU-C, we purified CFU-C from the peripheral blood of chronic myeloid leukemia(More)
Myeloid progenitor cells (colony- and cluster-forming cells in semisolid medium, CFU-GM) were purified from the peripheral blood of chronic myelogenous leukemia (CML) patients. Lymphocytes, monocytes, and most immature myeloid cells were simultaneously depleted with specific monoclonal antibodies using an erythrocyte rosette technique for cell separation.(More)
The identification of potent, highly selective orally bioavailable ghrelin receptor inverse agonists from a spiro-azetidino-piperidine series is described. Examples from this series have promising in vivo pharmacokinetics and increase glucose-stimulated insulin secretion in human whole and dispersed islets. A physicochemistry-based strategy to increase(More)
