Fertilized, high quality, human eggs also called oocytes at the eight (8) cell stage after three days. Mosaic image composed of 4 sections.
Abstract designed black, gray and white wallpaper background image for computer desktops.
Photomicrograph of one celled amoeba. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
The plant roots under the microscope
Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.
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.
Natural agate surfaces, suitable for backgrounds and wallpapers.
Several clusters of human Human Embryonic Kidney 293 cells in culture. These cells are a standard cell line used in biotechnology applications, for example to produce proteins. This view is as it appears through an inverted biological phase contrast microscope with 200x magnification.

False color image of diatom under the microscope
Trematode parasite under a microscope
Symbolic illustration of infectious viruses under the microscope, for example influenza viruses, smallpox, measles or similar. Medical research and investigation of diseases and healthcare concept.
Four, side view, X-ray pictures of a woman's two breasts. On the right, lateral breast there are two intramammary lymph nodes with fatty hilum measuring 0.5 and 0.6 cm respectively. No suspicious breast mass or auxiliary lymphadenopathy. Moderately dense breasts with 50 to 75 % glandular tissue.  Bi-RADS 2 : benign findings.
Microscopic image showing oxalate crystals from urine sediment, most common cause of kidney stones
Abstract Crystal background marble shot, nature pattern.
3D rendering illustration of a database icon
Photomicrograph of Paramecium caudatum. Consists of only one cell. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
view of vegetal cells through a 1000x microscope lens
Full size digital screening mammogram of a new breast tumor in the retroareolar region of the right breast causing nipple retraction. An ultrasound guided biopsy was performed diagnosing invasive ductal carcinoma. This is the most common type of breast cancer, accounting for nearly 80% of cases. Breast cancer treatment has come a long way in the last few decades, seeing more funding than any other human disease. The first step to a cure is catching it early with screening mammograms such as this case so that the tumor can be removed before it spreads (metastasizes) out of the breast.
An electron image represents several nanoparticles made of lipids (liposomes) containing an anticancer drug (doxorubicin)
Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.
Onion plant under salt water
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.
Uric acid crystal, Calcium oxalate dihydrate in urine sediment.
