Bone morphogenetic proteins (BMPs) are a group of growth factors also known as cytokines and as metabologens. 3D cartoon and Gaussian surface models, white background.
Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
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
Baryte or barite is a mineral consisting of barium sulfate. The baryte group consists of baryte, celestine, anglesite and anhydrite. 3d illustration

Fatty liver disease (steatosis) is a common condition caused by having too much fat build up in your liver. A healthy liver contains a small amount of fat. It becomes a problem when fat reaches 5% to 10% of your liver's weight.
The study of plant tissues under the microscope in the laboratory.
Photomicrograph of two rotifers. Rapidly rotating cilia at top of heads, internal organs visible. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
Squalane is a hydrocarbon derived by hydrogenation of squalene. 3d illustration
Molecular model of lactose, a disaccharide sugar in milk.
Uterus uterus infection. bacterial growth. 3d illustration

Isolated minoxidil chemical molecule structure in the white background 3d rendering
Urothelial carcinoma, high grade.  High-grade tumors have an aggressive appearance under a microscope and are assumed invasive in the kidney or ureter.
B-chain pentamer and A-chain subunit (green), 3D cartoon and Gaussian surface model, 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.
