Lily leaf c.s. under microscope
Bacteria pathogen - 3d rendered microbiology image. Illustrate of Lactobacillus Bulgaricus Bacteria, Microbacterium Tuberculosis Bacteria (MTB). Medical research, health-care concept. SEM (TEM) scanning view
3D cartoon and Gaussian surface models, PDB 5fwk, white background
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.
Phospholipid bilayer membrane structures that make up living cells and their contents. This is an image of membrane proteins in the membrane.\nThis image, which looks like a plastic model, evokes biology and biochemistry. It can be used as a cover for magazines, textbooks and presentation materials.\nThis image was not created by AI.
Acetylcholine receptors in the lipid layer of cell membrane.
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
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
Cells and cancer cells,Microscopic image of cells, 3d rendering, division of cancer cell
Natural agate surfaces, suitable for backgrounds and wallpapers.
Deacetoxycephalosporin-C synthase (DAOCS) is a mononuclear ferrous enzyme that transforms penicillins into cephalosporins. 3D cartoon and Gaussian surface models, chain instance color scheme, based on PDB 1uof, white background.
Liver Fluke Section under light microscope with white background
Embryonic stem cells in amniotic fluid as a concept science, biology and Cellular therapy. 3d rendering
Close-up shot of a petri dish for checking an antibiotic in the laboratory.
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.
anaplastic thyroid carcinoma with heterologous differentiation (leiomyosarcoma)
Biological protein and molecule, 3d rendering. 3D illustration.
Photomicrograph of two rotifers. Rapidly rotating cilia at top of heads, internal organs visible. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
3D cartoon and Gaussian surface models, chain id color scheme, PDB 7t3a, white background

Backgrounds of Bacteria and Mold under the microscope in Lab.
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.
Epithelioid mesothelioma is a cancer subtype caused by asbestos. It is the most common mesothelioma cell type, accounting for 50% to 70% of cases.
Blood cell formation from bone marrow.Acute lymphoblastic leukemia(ALL),fine with microscope(100x)
