The lymphoid organs and bone marrow are predominantly composed of lymphoid and myeloid tissue respectively. These tissues are supported mostly by reticular tissue which forms a reticulum. The thymic lymphoid tissue is supported by an analogous reticulum, which has an epithelial (ectodermal) origin. In...
such extracellular materials as hair and nails are composed of protein. So also iscollagen, the fibrous, elastic material that makes up much of the body’s skin, bones, tendons, and ligaments. Proteins also perform numerous functional roles in the body. Particularly important are cellular proteins...
Alternative approaches to animal testing include the use of organoids, which are biological models for specific organs or tissues that are composed of living cells or biomaterials. The organoid should have similar functionality with the native organ or tissue for toxicology testing to be successful. ...
is composed of the body of an organization, distributed in various tissues and organs and bones, every piece of muscle innervating muscles and nerves, nutrition muscle blood vessels, muscle separated packages, the connective tissue connects muscle and bones together to form an organ. Total of ...
Every type of biologic effect of radiation, irrespective of its precise nature, results from injury to the cell, the microscopic building block of which all living organisms are composed. It therefore seems useful to open a review of such effects with a discussion of the action of radiation on...
of tonsils, the palatine and lingual tonsils. A palatine tonsil is one of a pair of structures located laterally in the oropharynx. The lingual tonsil is located at the base of the tongue. Similar to the pharyngeal tonsil, the palatine and lingual tonsils are composed of lymphoid tissue, ...
(duckweed family). Some fruiting bodies contain non-ovary tissue and are sometimes called pseudocarps. The sweet flesh of apples and pears, for example, is composed not of the pericarp but the receptacle, or upper portion, of the flowering shoot to which petals and other floral organs are ...
With the PEGASOS method, we were able to image intact mouse head composed of bones, teeth, brain, muscles, and other tissue types. We also imaged intact mouse brain and traced individual axons and neurons over a long distance. We were able to image through the vertebrae to identify ...
The field of liver regenerative medicine is composed of a broad range of approaches, including cell therapy, immunomodulation therapy, and liver tissue engineering. These approaches are aimed toward replacing or regenerating tissue to restore functionality in failing livers.1, 2, 3, 4, 5, 6 Some...
Current high-throughput systems for drug discovery and toxicology applications rely on indirect measurement of cell health and function, such as biomarkers and RNA expression analysis. The field would benefit from more advanced systems that are low cost and utilize defined media to support multiple ...
