Bone marrow plasma cells .Plasma cell neoplasms are diseases in which the body makes too many plasma cells. Plasma cell neoplasms can be benign or malignant. Diagnosed with Immunostain CD138 positive.
Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.
plant Zea Stem C.S. under light mircoscope with white background
Cross-section Dicot, Monocot and Root of Plant Stem under the microscope for classroom education.
Natural agate surfaces, suitable for backgrounds and wallpapers.
Cross sections of dicot plant root under light microscope view for botany education.
In vitro bacterial culture
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
