Historically in photolithography for the mass production of integrated circuit devices, there was a distinction between the term photoreticle or simply reticle, and the term photomask. In the case of a photomask, there is a one-to-one correspondence between the mask pattern and the wafer pattern.
A reticular cell is a type of fibroblast that synthesizes collagen alpha-1(III) and uses it to produce extracellular reticular fibers.Reticular cells provide structural support, since they produce and maintain the thin networks of fibers that are a framework for most lymphoid organs.
A reticle, or reticule [1] [2] also known as a graticule, is a pattern of fine lines or markings built into the eyepiece of an optical device such as a telescopic sight, spotting scope, theodolite, optical microscope or the screen of an oscilloscope, to provide measurement references during visual inspections.
Reticule can refer to: Reticle, fine lines in the eyepiece of a sighting device; Reticule (handbag), a type of small handbag This page was last edited on 29 ...
Specialized cells can have a lot of smooth endoplasmic reticulum and in these cells the smooth ER has many functions. [6] It synthesizes lipids, phospholipids, [19] [20] [21] and steroids. Cells which secrete these products, such as those in the testes, ovaries, and sebaceous glands have an abundance of smooth endoplasmic reticulum. [22]
The preferred AE term is "reticle", sometimes "reticule", which is also occasionally found in BE. It is used by most authors to denote exactly the same thing as graticule, though the dictionary definition (Webster) is somewhat different: "Reticle — a system of lines, wires, or the like, in the focus of the eyepiece of an optical instrument."
One significant cell-line cross contaminant is the immortal HeLa cell line. HeLa contamination was first noted in the early 1960s in non-human culture in the USA. Intraspecies contamination was discovered in nineteen cell lines in the seventies. In 1974, five human cell lines from the Soviet Union were found to be HeLa.
A stem-cell line is distinctly different from an immortalized cell line, such as the HeLa line. While stem cells can propagate indefinitely in culture due to their inherent properties, immortalized cells would not normally divide indefinitely but have gained this ability due to mutation. Immortalized cell lines can be generated from cells ...
