BACKGROUND Maintaining the quality of cryopreserved cord blood is crucial. In this pilot study, we describe the results of the internal quality control program for a cord blood bank thus far. METHODS Donated cord blood units unsuitable for transplantation were selected for internal quality control once a month. One unit of cord blood, aliquoted into 21 capillaries, was cryopreserved and thawe...
Cell-cell fusion is essential for fertilization. For fusion of walled cells, the cell wall must be degraded at a precise location but maintained in surrounding regions to protect against lysis. In fission yeast cells, the formin Fus1, which nucleates linear actin filaments, is essential for this process. In this paper, we show that this formin organizes a specific actin structure-the actin fusi...
The bone marrow aspiration test conventionally has been performed by visual methods, using a light microscope, because automatic blood cell analyzers cannot adequately capture erythroblasts and immature granulocytes (IGs) (Tatsumi et al.: Osaka City Med J 1988;34:135-146; Tatsumi et al.: Am J Clin Pathol 1986;86:50-54). With the development of the XE-2100 automatic blood cell analyzer (Sysmex C...
We assessed the cytokine combinations that are best for ex vivo expansion of cord blood (CB) and the increment for cell numbers of nucleated cells, as well as stem cells expressing homing receptors, by an ex vivo expansion of cryopreserved and unselected CB. Frozen leukocyte concentrates (LC) from CB were thawed and cultured at a concentration of 1 x 10(5)/mL in media supplemented with a combin...
The aim of this study was to imply the possibilities of the urgent cytological examination of synovial fluids in differential diagnosis of arthropathies and to motivate the clinicians to use this method. It gave valuable information particularly with respect to differentiate the inflammatory and non-inflammatory joint diseases. This study included 115 synovial fluids obtained by fine needle asp...
A 24-year-old male presented with abdominal pain, fever, and palpable splenomegaly. His differential count revealed myelocytes, metamyelocytes, and nucleated red cells. A bone marrow biopsy confirmed a diagnosis of hepatosplenic gamma delta T-cell leukemia/lymphoma. We describe here our center's diagnostic and treatment approach for this rare leukemia.
Lamellipodia are dynamic actin-rich cellular extensions that drive advancement of the leading edge during cell migration. Lamellipodia undergo periodic extension and retraction cycles, but the molecular mechanisms underlying these dynamics and their role in cell migration have remained obscure. We show that glia-maturation factor (GMF), which is an Arp2/3 complex inhibitor and actin filament de...
In this paper, we seek to model the deformation of nucleated cells by single diode-laser bar optical stretchers. We employ a recently developed computational model, the Dynamic Ray-Tracing method, to determine the stress distribution induced by the applied optical forces on a capsule encapsulating a nucleus of different optical properties. These forces are shape dependent and can deform real no...
