Leiden leaf c.s. under microscope
anaplastic thyroid carcinoma with heterologous differentiation (leiomyosarcoma)
Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background
Photomicrograph of algae, Cosmarium turpinii, a desmid. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
plant Zea Stem C.S. under light mircoscope with white background
Micrograph of rat brain. Science cross section.
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.

Lily leaf c.s. under microscope
Chronic viral hepatitis B. Chronic hepatitis B infection lasts six months or longer. It lingers because your immune system can't fight off the infection. Chronic hepatitis B infection may last a lifetime, possibly leading to serious illnesses such as cirrhosis and liver cancer.

Cheyletiella blakei Mite - Small Cat pest view under a microscope
Freshwater aquatic zooplankton and algae under microscope view
Myxoid liposarcoma.  Myxoid/round cell liposarcoma, or MRCLS, is one of several types of liposarcoma. Liposarcoma is a rare cancer that grows in the cells that store fat in the body. MRCLS usually grows in the arms and legs. These tumors grow slowly, and they can spread to other parts of the body
amazing inhabitants of the microworld under a microscope
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.
Paps smear analysis: Superficial squamous cell, metaplastic squamous cell, koilocytes cell. HPV related change
Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens.  Depth of focus is extremely shallow (just a few microns).  Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Host cells with spores (mold) are inside wood under the microscope for education.

Spirogyra algae (filamentous green algae) under the microscope - optical microscope x400 magnification
Plasmacytoid urothelial carcinoma (PUC) is a unique variant of invasive urothelial carcinoma characterized by tumor cells that exhibit a striking resemblance to plasma cells, and it is known to have an aggressive behavior.
Toxoplasma gondii oocyst under the microscope, isolated
Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.
Microscopic photo of a thin section of calcareous tufa of Holocene age.
