- Ribosomes happen to be basophilic.]. Chief cells of the stomach secrete the digestive enzymes (pepsins) of the stomach and have the typical appearance of serous-secretory epithelial cells. Secretory vesicles (containing pepsinogen) are clearly visible in the apical cytoplasm of chief cells.

- Most of this section is composed of darkly staining acini (balls or clusters of cells) that comprise the parenchyma (dominant cell type) of this organ. Our focus here is on the relatively small, pale staining ducts that can be found at low power within the connective tissue separating the acini.

Somatic Cells: Definition, Examples & Types All living creatures are made up of cells. In plants and animals, there are two major categories of cells: somatic cells and reproductive cells, known as germ cells or gametes. In humans and other animals, they are the egg and sperm cells. All other cells in the body are somatic cells.

What's in Your Stomach's Gastric Juice? Each of the glands contains cells that make specific components that together are called the gastric juices. Neck cells secrete bicarbonate and mucous, parietal cells secrete hydrochloric acid, chief cells secrete pepsinogen, and enteroendocrine cells secrete various hormones.

Parathyroid chief cell Parathyroid chief cells are one of the two cell types of the parathyroid glands, along with oxyphil cells. The chief cells are much more prevalent in the parathyroid gland than the oxyphil cells. It is perceived that oxyphil cells may be derived from chief cells at puberty, as they are not present at birth like chief cells. Chief cells appear as a dark purple in an H&E stain, with the oxyphil cells staining as a lighter pink. They are polygonal in shape with a round nucleus.

List of distinct cell types in the adult human body basal cell (stem cell) of epithelia of cornea, tongue, oral cavity, esophagus, anal canal, distal urethra and vagina; Urinary epithelium cell (lining urinary bladder and urinary ducts) Nervous system. There are nerve cells, also known as neurons, present in our human body. They are branched out. These cells make up nervous tissue. A neuron consists of a cell body with a nucleus and cytoplasm, from which long thin hair-like parts arise. Sensory transducer cells. Auditory inner hair cell of organ of Corti; Auditory outer hair cell of organ of Corti; Basal cell of olfactory epithelium (stem cell for olfactory neurons)

Digestive enzyme 1 It is produced by the stomach cells called chief cells in its inactive form pepsinogen, which is a zymogen. 2  Pepsinogen is then activated by the stomach acid into its active form, pepsin. 3  Pepsin breaks down the protein in the food into smaller particles, such as peptide fragments and amino acids.

- The water-conducting cells of the primary xylem are dif-ferentiated as a solid core in the center of young dicotroots. In a cross-section of a dicot root, the central core ofprimary xylem often is somewhat star-shaped, with one ortwo to several radiating arms that point toward the pericy-cle (figure 38.19).

CellsËsel Some cells, such as skin cells, divide and reproduce quickly. Other cells, such as certain nerve cells, do not divide or reproduce except under unusual circumstances. Some cells, especially glandular cells, have as their primary function the production of complex substances, such as a hormone or an enzyme.

NK cell The form of cell composing many primitive unicellular organisms, such as bacteria. Prokaryotic cells do not have nuclei, which are partitioned by an intracellular membrane; instead the DNA forms one main coil in the cell cytoplasm.lara cell. A cuboidal epithelial cell found in the lining of the terminal and the respiratory bronchioles of the lungs. Clara cells are nonciliated, and they secrete surfactant, like the type II alveolar epithelial cells found deeper in the bronchial tree.

Cell There are two basic kinds of cells: prokaryotic cells and eukaryotic cells. Prokaryotes, bacteria and archaea, are simple cells that have no cell nucleus. They do have bacterial microcompartments. Eukaryotes are complex cells with many organelles and other structures in the cell.

Digestive enzyme There are four types of cells in the stomach: 1  Parietal cells: Produce hydrochloric acid and intrinsic factor. 2  Gastric chief cells: Produce pepsinogen. 3  Mucous neck and pit cells: Produce mucin and bicarbonate to create a neutral zone to protect the stomach lining from the acid or irritants in the stomach chyme.

What is 'Protected Cell Company (PCC)' DEFINITION of 'Protected Cell Company (PCC)'. A corporate structure in which a single legal entity is comprised of a core and several cells that have separate assets and liabilities.The protected cell company, or PCC, has a similar design to a hub and spoke, with the central core organization linked to individual cells.Each cell is independent of each other and of the company’s core, but the entire unit is still a single legal entity. Next Up.he protected cell company, or PCC, has a similar design to a hub and spoke, with the central core organization linked to individual cells.

- Lastly, parietal cells synthesizedand secrete intrinsic factor which aids in the absorption of vitamin B12 by the ileum. Chief cells (B or arrow)are located, in cluster, at the base of the glands. They synthesize and secret hydrolytic enzymes, which areactivated at acid pH. These enzymes include gastric lipase, rennin and pepsin, which is secreted aspepsinogen and activated in the lumen. Pepsin hydrolyzes proteins. Rennin breaks down milk proteins andlipase initiates the digestion of fats.

Pancreatic Acinar Cell Cancer Pancreatic Acinar Cell Cancer. Acinar cell neoplasms arise from the acinar cells of the pancreas. Normal acinar cells are the primary cells of the exocrine pancreas and are responsible for secreting various enzymes. These tumors are distinct from the more common adenocarcinomas of the pancreatic ducts.

You Gotta Know These Organelles Nucleus The nucleus is the command central of the cell because it contains almost all of the cell's DNA, which encodes the information needed to make all the proteins that the cell uses. The DNA appears as chromatin through most of the cell cycle but condenses to form chromosomes when the cell is undergoing mitosis.

Common Terms Beta cell: A type of cell in the pancreas. Within the pancreas, the beta cells are located in areas called the islets of Langerhans where they constitute the predominant type of cell. The beta cells make and release insulin, a hormone that controls the level of glucose (sugar) in the blood.

- You have many types of specialized cells in your body, but they can be divided into two major groups: somatic cells and germ cells. Somatic cells (soh-MAT-ihk), also called body cells, make up most of your body tissues and organs. For example, your spleen, kidneys, and eyeballs are all made entirely of body cells.

Boston Children's Hospital There are several types of pluripotent stem cells, including embryonic stem cells. At Children’s Hospital Boston, we use the broader term because pluripotent stem cells can come from different sources, and each method creates a cell with slightly different properties. But all of them are able to differentiate, or mature, into the three primary groups of cells that form a human being:

Theory To getting the cells for culture must be isolated from a donor animal tissue or organ. The cell culture may be divided into three according to their history: 1) primary, 2) secondary and 3) continuous cell culture. The primary and secondary cells are usually diploid cells.Primary cell lines derived directly from an intact tissue like animal’s embryo or kidney.Secondary cells are derived from primary cultures. And the continuous cell lines are usually derived from malignant tissue.o getting the cells for culture must be isolated from a donor animal tissue or organ.
