Ultrastructural and Cytochemical Observations
Five canine cutaneous histiocytomas were studied by electron microscopy and esterase cytochemistry. The tumor cells contained irregular nuclei, characteristic lysosomal granules, and perinuclear microfilaments. The cells showed activity with anaphthyl acetate esterase stains. These characteristics are evidence that this tumor originates from the mononuclear phagocyte system. Canine cutaneous hi...
متن کاملDendritic cells and interleukin-2: cytochemical and ultrastructural study.
The aim of the present study was to verify the effect of IL-2 on dendritic cell (DC) differentiation. Various cytokines have been indicated as factors inducing DC differentiation, but no data about the interleukin-2 (IL-2) effect on DC differentiation have been reported. Monocytes isolated from peripheral blood were treated in vitro with the following factors: IL-2, IL-4, GM-CSF and G-CSF alone...
متن کاملUltrastructural cytochemical analyses of nuclear functional architecture.
For many years, ultrastructural cytochemistry has been a major tool for investigating the relationships between the structure and the functions of the cell nucleus. This article shortly reviews the contributions of transmission electron microscopy to the in situ studies of intranuclear distribution of chromatin domains and of essential nuclear functions, such as DNA replication, transcription a...
متن کاملCytochemical profile of B and T leukaemic lymphocytes with special reference to acute lymphoblastic leukaemia.
The PAS and acid phosphatase reactions showed a different pattern of positivity in the cells of lymphoproliferative disorders according to their B or T cell nature. In B-cell leukaemias (chronic lymphocytic and prolymphocytic) a low proportion of lymphocytes gave a positive result with the acid phosphatase reaction, while the majority were PAS positive in granular form. In contrast, in the T-pr...
متن کاملA Histochemical and Cytochemical Study
Localization of 5’-nucleotidase in the frog retina was investigated using histochemical and cytochemical techniques. Light-microscopic observations revealed the presence of this enzyme in the inner retinal layers (the nerve fiber layer, ganglion cell layer, and inner plexiform layer). Ultrastructural investigations revealed that the enzyme activity is associated with the plasma membranes of the...
