Carcinoid tumors are a type of slow-growing cancer that can arise in several places throughout your body. Carcinoid tumors, which are one subset of tumors called neuroendocrine tumors, usually begin in the digestive tract (stomach, appendix, small intestine, colon, rectum) or in the lungs. Site: Ovary
Microscope photo of the cells from a young broad bean steam (Vicia faba).
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.
After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.

Characteristics of fungi living in wood as a group, are polyphyletic under the microscope for education.
plant Flower bud of Lilium brownii var.viridulum T.S.\nunder light mircoscope with white background
Cross section leaf of plant under the light microscope view for botany education.
Burkitt lymphoma is a form of non-Hodgkin's lymphoma in which cancer starts in immune cells called B-cells. Recognized as a fast growing human tumor, Burkitt lymphoma is associated with impaired immunity and is rapidly fatal if left untreated.
Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background
Haematocysts of single-celled green algae,
Metastatic plasmacytoma, metastatic undifferentiated sarcoma. Microscopically show cellular material of mostly plasmacytiod cells. atypical mitoses are present. plasma cell tumor.
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.
Histological Pancreas human, Liver human, Vermiform appendix human and Kidney Human under the microscope for education.
Quantum Gravity 3d rendered image of a comprehensive exploration of Quantum Gravity theories. String theory, loop quantum gravity (LOG), causal dynamical triangulation, twistor theory, gravitational waves, spacetime, gravity waves, quantum mechanics, quantum entanglement concepts.
3D computer generated fractal abstract geometric knit object details isolated on infinite background
Colored plant cells with damages caused by a parasitic animal under the microscope.
