"Endostatin" Natural Recordings by Native Speakers
Endostatin is a naturally occurring protein fragment that is derived from collagen XVIII. It is a potent angiogenesis inhibitor, meaning it prevents the growth of new blood vessels. Endostatin is found in the extracellular matrix of tissues and is thought to play a role in regulating vessel growth and stability.
Endosomes are a type of membranous cell organelle found in the cytoplasm of eukaryotic cells. They are small, vesicle-like structures that are derived from the cell membrane and function in the processing and degradation of newly internalized materials, such as proteins, lipids, and other substances. Endosomes can be thought of as sorting stations where the cell's internalized materials are processed and routed to their final destinations within the cell.
Endosomolytic refers to an agent or substance that is able to disrupt or break down endosomes, which are small membrane-bound sacs found within cells that are involved in the process of cellular digestion and recycling of proteins and other materials.
The endosperm is the white starchy part of a grain, such as wheat, rice, or corn, that surrounds the embryo and provides nutrition during seed germination and seedling growth. It is the largest component of a grain and is usually composed of carbohydrates, including starch, fiber, and proteins.
Endospermic refers to a characteristic of a plant seed having its seeds with little or no endosperm for the nutrition of the embryo, the opposite of endospermous. In endospermic seeds, the embryo is able to gain its nutrition from the seeds' outer layer, the testa, rather than from an endosperm starch reserve.
Endospore: A type of dormant, highly resistant spore produced by certain bacteria, such as Clostridium and Bacillus, in response to adverse environmental conditions. Endospores are able to survive extreme temperatures, radiation, and chemical treatment, and can remain dormant for extended periods of time, allowing the bacteria to persist and potentially resurface when conditions improve.
To endorse or support something, especially by giving one's official approval or recommendation: "The company endorses the new product."
Endostea is a noun that refers to a genus of land snails in the family Charopidae. These snails are characterized by their glandular epiphragm, which is a protective layer on the opening of their shell.
The endosteum is a layer of epithelial and connective tissue that lines the internal surface of bone cavities and is a site of bone formation and repair. It is a type of connective tissue that is responsible for regulating the formation and resorption of bone tissue. The endosteum is composed of two layers: a surface layer of flat cells called the periosteum, and a deeper layer of cells that produce and respond to growth factors. The endosteum plays a crucial role in maintaining bone health by regulating bone formation, resorption, and remodeling.
The endostium is a small, thin-walled chamber that lies at the base of the mesonephros, which is a type of kidney that develops in mammals. It is a temporary structure that is present during embryonic development and is involved in the formation of the adult kidney.
Endostoma is a rare or obsolete word that refers to the lining or innermost layer of an organ or structure, especially the mucous membrane lining the inner surface of a cavity or organ.
An endostome is a type of parasitic crustacean that lives inside the bodies of other animals, particularly mollusks and echinoderms. It feeds on the nutrients absorbed by its host from food, often without being noticed.
Endostosis is a rare medical condition in which a foreign object, such as a splinter or a metal fragment, embeds itself within the bone. It is often treated surgically to remove the object and repair any damage to the surrounding tissue.
The endostyle is a pair of epithelial ducts found in the esophagus of some aquatic invertebrates, such as tunicates and larval stages of some chordates. It is responsible for producing pharyngeal glands, which are thought to be a precursor to the thyroid gland in vertebrates. In other words, the endostyle is a structure that played a key role in the evolution of the thyroid gland in vertebrates.
