Neuroendocrine carcinoma well differentiated (carcinoid) rectum with immunostain synaptophysin
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
Metastatic plasmacytoma, metastatic undifferentiated sarcoma. Microscopically show cellular material of mostly plasmacytiod cells. atypical mitoses are present. plasma cell tumor.
Chronic appendicitis pathology under light microscopyzoom in different areas.
Aerial view of loyster farm by Ardara, County Donegal - Ireland.
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.
Host cells with spores (mold) are inside wood under the microscope for education.
Texture Pattern Design on Banknote
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).
Angiosarcomas of the breast are a type of soft tissue sarcoma. They start in cells in the walls of blood vessels. Breast angiosarcomas are very rare and it is difficult to find much information about them.
Immunotherapy of Alzheimer's disease: Monoclonal antibody (light blue) bound to an amyloid beta peptide (orange),  that is aggregated to amyloid beta fibrils, which build up amyloid plaques.

Photomicrograph of two rotifers. Rapidly rotating cilia at top of heads, internal organs visible. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
High Vaginal Swab (HVS) Gram Stain: Photomicrograph showing Bacterial vaginosis (BV).
Lymphocytic myocarditis. Myocarditis is an inflammation of the heart muscle. Lymphocytic refers to the type of cell seen in the affected tissue. A lymphocyte is a type of immune function cell.
HER2 (light blue)  locked in the inactive conformation by Trastuzumab (left) and Pertuzumab. Trastuzumab has drastically improved the prognosis of HER2-positive breast cancer patients.

Host cells with spores (mold) are inside wood under the microscope for education.
Photomicrograph of rotifer. Rapidly rotating cilia at top of head, internal organs visible. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Light micrograph of an unstained iris showing the localization of pigment cells. The melanin pigment is concentrated in the back surface of the iris stroma, near the pigment epithelium (right). Between both, there is a clear band that corresponds to the iris dilator muscle. The anterior surface shows a lower concentration of pigment.
