3d animal cell on black background
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.
The Raf/MEK/ERK (MAPK) propagates growth signals in the cell. Misregulation can lead to cancer.\nThe red dots on the active EGFR are phosphorylated tyrosines. PDB entries: 1egf, 1nql, 1m17, 2jwa, 3njp, 2gs6, 1gri, 1xd2, 3ksy, 5p21, 6xi7, 6q0j, 2y4i,
Microscopic photograph of a professionally prepared slide demonstrating vulvar malignant melanoma. Melanomas of the vulva and vagina are rare, accounting for no more that 2% of melanomas among women. Melanoma of the vulva behaves like melanoma in any other location and may affect a much younger population.
Histological Cerebellum human, Sympathetic ganglion human And Spinal cord human under the microscope for education.
Photomicrograph of two rotifers. Rapidly rotating cilia at top of heads, internal organs visible. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.

Microscopic photo of a thin section of calcareous tufa of Holocene age.
Luxury stone background, nature pattern for use.
Pine mature wood cross section. Light microscope slide with microsection of an evergreen conifer in the genus Pinus. Plant anatomy. Biology. Photo.
Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
Internal structure of an animal cell, 3d rendering. Section view. Computer digital drawing.
Intricate bubble texture macro in bright colors for abstract background. Liquid bubbles lit from below with colors injected into the liquid as a design or art abstract.
Low magnification micrograph of the gastric mucosa showing the surface mucous epithelium, the gastric pits and the fundic glands with many pink parietal cells.
plant rape flower cross section under light mircoscope with white background
Embryonic stem cells in amniotic fluid as a concept science, biology and Cellular therapy. 3d rendering
Slice of natural crystal for patterns and textures use with high resolution.
Tissue of Small intestine (Duodenum), Large intestine Human and Stomach Human under the microscope in Lab.
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.
Metastatic plasmacytoma, metastatic undifferentiated sarcoma. Microscopically show cellular material of mostly plasmacytiod cells. atypical mitoses are present. plasma cell tumor.
Coloured transmission electron micrograph (TEM) of a small arteriole showing, from lumen: endothelium (magenta), discontinuous internal elastic lamina (blue), cross-sectioned smooth muscle fibers (cytoplasm, red, nucleus, light yellow) and connective tissue of adventitia (green).
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.

3D illustration of a cluster of Fat cells isolated on white.
Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.
Cotton plant root, under the light microscope. Longitudinal section through the root of Gossypium hirsutum, upland or also Mexican cotton. Light micrograph at 20X magnification. Isolated, over white.
