| cell fate | <embryology> Of an embryonic parent (progenitor) cell or cell type, the range and distribution of differentiated tissues formed by its daughter cells. For example: cells of the neural crest differentiate to form among other things) cells of the peripheral nervous system. (26 Mar 1998) |

| fate | 1. A fixed decree by which the order of things is prescribed; the immutable law of the universe; inevitable necessity; the force by which all existence is determined and conditioned. "Necessity and chance Approach not me; and what I will is fate." (Milton) "Beyond and above the Olympian gods lay the silent, brooding, everlasting fate of which victim and tyrant were alike the instruments." (Froude) 2. Appointed lot; allotted life; arranged or predetermined event; destiny; especially, the final lot; doom; ruin; death. "The great, th'important day, big with the fate Of Cato and of Rome." (Addison) "Our wills and fates do so contrary run That our devices still are overthrown." (Shak) "The whizzing arrow sings, And bears thy fate, Antinous, on its wings." (Pope) 3. The element of chance in the affairs of life; the unforeseen and unestimated conitions considered as a force shaping events; fortune; especially, opposing circumstances against which it is useless to struggle; as, fate was, or the fates were, against him. "A brave man struggling in the storms of fate." (Pope) "Sometimes an hour of Fate's serenest weather strikes through our changeful sky its coming beams." (B. Taylor) The three goddesses, Clotho, Lachesis, and Atropos, sometimes called the Destinies, or Parcaewho were supposed to determine the course of human life. They are represented, one as holding the distaff, a second as spinning, and the third as cutting off the thread. Among all nations it has been common to speak of fate or destiny as a power superior to gods and men swaying all things irresistibly. This may be called the fate of poets and mythologists. Philosophical fate is the sum of the laws of the universe, the product of eternal intelligence and the blind properties of matter. Theological fate represents Deity as above the laws of nature, and ordaining all things according to his will the expression of that will being the law. Synonym: Destiny, lot, doom, fortune, chance. Origin: L. Fatum a prophetic declaration, oracle, what is ordained by the gods, destiny, fate, fr. Fari to speak: cf. OF. Fat. See Fame, Fable, Ban, and cf. 1st Fay, Fairy.

| fate map | <embryology> Diagram of an early embryo (usually a blastula) showing which tissues the cells in each region will give rise to (i.e. Their developmental fate). Fate maps are normally constructed by labelling small groups of cells in the blastula with vital dyes and seeing which tissues are stained when the embryo develops. (18 Nov 1997) |
| specialty chemicals and products | Chemicals and chemical products used in a research, industrial, or household setting. Included here are the specific drug preparations, as well as the substances involved in the manufacture and stabilization of pharmaceutical preparations and agricultural agents. (12 Dec 1998) |
| inorganic chemicals | A broad class of substances encompassing all those that do not include carbon and its derivatives as their principal elements. However, carbides, carbonates, cyanides, cyanates, and carbon disulfide are included in this class. (12 Dec 1998) |
| organic chemicals | A broad class of substances containing carbon and its derivatives. Many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements. They exist in either carbon chain or carbon ring form. (12 Dec 1998) |
| laboratory chemicals | Chemicals necessary to perform experimental and/or investigative procedures and for the preparation of drugs and other chemicals. (12 Dec 1998) |
| biological | Pertaining to biology. (18 Nov 1997) |
| biological agent | <microbiology> A disease-causing microorganism or virus, or other toxic biological matter, which is used as a weapon during war. (21 Mar 1998) |
| biological assay | <technique> Once a pharmaceutical protein is isolated from the cells in which it was grown, researchers perform tests to measure the protein's biological activity. It must maintain a certain minimal level of biological activity to be used for animal or clinical testing or, later, for market. Researchers also test to confirm that the isolated protein is identical to the desired protein. (21 Mar 1998) |
| biological assessment | A specific process required as part of an environmental assessment. An evaluation of potential effects of a proposed project on proposed, endangered, threatened, and sensitive animal and plant species and their habitats. (05 Dec 1998) |
| biological availability | The extent to which the active ingredient of a drug dosage form becomes available at the site of drug action or in a biological medium believed to reflect accessibility to a site of action. (12 Dec 1998) |
| biological chemistry | The scientific study of the chemistry of living cells, tissues, organs and organisms. (09 Oct 1997) |
| biological clock | <biology, physiology> An internal biological mechanism which controls certain biological rhythms and biocycles, such as metabolism, sleep cycles, photosynthesis. (21 Mar 1998) |
| biological clocks | The physiological mechanisms that govern the rhythmic occurrence of certain biochemical, physiological, and behavioural phenomena in plants and animals. The pineal gland, which receives input from the optic nerves and connects to the hypothalamus, may be the biological clock in humans. (12 Dec 1998) |
