Following the initial isolation in 1958 of epithelial cells from the kidney tubule of an adult Cocker Spaniel dog by Stewart H. Madin and Norman B. Darby, Jr., [3] the cell line bearing their name was employed primarily as a model for viral infection of mammalian cells.
Dogs have ear mobility that allows them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate, raise, or lower a dog's ear. A dog can identify a sound's location much faster than a human can, as well as hear sounds at four times the distance. [41] Dogs can lose their hearing from age or an ear infection. [42]
Cell shape changes as a function of mitotic phase.Shown is an example of a HeLa cell cultured on a glass surface. For visualization of DNA and mitotic phase assignment, the cell expresses Histone H2B-GFP to provide fluorescent labeling of chromosomes.
Heinz bodies appear as small round inclusions within the red cell body, though they are not visible when stained with Romanowsky dyes. They are visualized more clearly with supravital staining [ 5 ] [ 6 ] (e.g., with new methylene blue , crystal violet or bromocresol green ).

A peripheral blood mononuclear cell (PBMC) is any peripheral blood cell having a round nucleus. [1] These cells consist of lymphocytes (T cells, B cells, NK cells) and monocytes, whereas erythrocytes and platelets have no nuclei, and granulocytes (neutrophils, basophils, and eosinophils) have multi-lobed nuclei. In humans, lymphocytes make up ...
From incredible recoveries to puzzling diagnoses, medical cases reveal the sheer complexity and resilience of the human body. They offer a glimpse into the challenges and triumphs of healthcare.
Pleomorphism is a term used in histology and cytopathology to describe variability in the size, shape and staining of cells and/or their nuclei. Several key determinants of cell and nuclear size, like ploidy and the regulation of cellular metabolism , are commonly disrupted in tumors . [ 1 ]
