Welcome to our Scientific Image Gallery. Here you can find real-life examples of cell images, mostly (but not only) from peripheral blood films, that illustrate typical morphologic characteristics pointing to specific conditions or disorders. This constitutes their diagnostic value.

<p>At low magnification, a drop of saliva is easily detected. When enlarged considerably, it might cause confusion.</p>
<p>Echinocytes ('sea urchin cells') of a healthy individual resulting from prolonged storage of the EDTA blood (24 hours).</p>
<p>Large number of echinocytes of a healthy individual resulting from prolonged storage of the EDTA blood (48 hours).</p>
<p>The edge of a correctly prepared blood film from a normal blood sample. Relatively few white blood cells can be seen in this example.</p>
<p>The endothelial cells are part of the vascular wall, which was damaged during venepuncture. (Blood coagulation was activated during the process: on the bottom left a fibrin fibre can be recognised.)</p>
<p>Size: 12-17 µm </p> <p>Nucleus: usually bilobed with visible filament </p> <p>Cytoplasm: weekly basophilic containing coarse reddish-orange granulation packing the cytoplasm </p> <p>Function: Phagocytosis, chemotaxis, mortification of parasites, inhibition of mastcell degranulation, eutralization of histamine</p>
<p>Epithelial cells in a drop of saliva containing streptococci.</p>
<p>Pronounced erythrocytosis (polyglobulia) can often already be recognised after sedimentation of the red blood cells. Left tube: haematocrit 82%, right tube: haematocrit 39%.</p>
<p>The bone marrow cytology (May-Grünwald-Giemsa stain) of a patient with ET shows a clear increase in exceptionally large megakaryocytes.</p>
