Supportive Internal Cells (SIC) are cells that support the internal structure of the body. They perform various functions, such as maintaining the shape of organs and tissues, regulating metabolism, and protecting against damage.
KPIs are an integral part of all living organisms and play an important role in their functioning. They may vary in shape and size, but they all have common characteristics, such as the presence of a cytoskeleton, which ensures their mobility and resistance to external influences.
One of the most well-known groups of CPIs are mesenchymal cells. They are formed from the mesoderm and are the basis for the development of connective tissue, including cartilage, bone, tendons and ligaments. Mesenchymal cells are also involved in wound healing and tissue repair after injury.
Another example of CPI are epithelial cells. They form a layer of cells that covers the surfaces of organs and protects them from external influences. Epithelial cells also play an important role in maintaining homeostasis by regulating metabolism and the release of various substances.
In addition, CPIs can include different types of blood cells, such as red blood cells, white blood cells and platelets. These cells transport oxygen and nutrients throughout the body, as well as protect against infections and other external threats.
Overall, KPIs play a key role in maintaining health and normal body function. Their study and understanding can help in the development of new methods of treatment and prevention of various diseases.
Cells supporting internal
The cells that support the internal cavity of various organs (in particular, the gastrointestinal tract - see below) and other organs in disease are associated with the functioning of the internal organs, providing their internal support, on which the health of the body depends. A cavity filled with fluid (gastric juice, urine, etc.) is called intracavitary. It is found in many organs of mammals, most often in striated muscles, ducts, and interfiber spaces of connective tissue. At the same time, these elements are often called digestive glands, hyaline bodies, and dental bodies. In this regard, it is fair to sometimes call them internal glands. 1. Cells of the internal cavity of the tongue. They are present in the mucous membrane of the dorsal part of the tongue. Located in the deep fibers of the submucosal layer. These cells secrete mucus that performs a protective function (protective saliva). By releasing mucus on the surface, it reduces irritation with the tip of the tongue. 2. Cells of the internal glands of the stomach and intestines Cell lines of the integumentary epithelium of the human stomach (HFE) have been cultured, which form well-defined monolayer cultures. The remaining cell lines, especially those obtained from the glands of the gastrointestinal tract, turned out to be of little use for this purpose. Moreover, in order to cultivate the gastro-enteric epithelium of various parts of the gastrointestinal tract in vitro, a set of series of models is required, which allows one to obtain satisfactory results even when cell proliferation is suppressed by a supraduodenal blood transplant. 3. Digestive function of the pancreas Performed by the exocrine and endocrine parts of the pancreas. The excretory part is a large number of acinar glands with protein secretions. They are synthesized from the blood and enter the acinar glands of the epithelial type, where they are converted into a coli-globular compound. It enters the capillaries of the terminal ductal system of the gland and, under pressure, is converted into protein secretions in the pancreatic juice. The secretory granules are centrifuged and disappear. These granules are identified as zymogens containing pairs of contacts between bipolar cells of the epithelial wall of the basal cisterns. The granule bipolar cell bridges to form sawtooth synapses that transmit the effects of secretions. Secretion is then completed by simultaneous destruction of the granule and mitosis through the process of vesicles into the parenchyma of epithelial cells. Glucose, albumin and water are secreted through the gutters of Bognal
