DonnéeUne donnée est ce qui est connu et qui sert de point de départ à un raisonnement ayant pour objet la détermination d'une solution à un problème en relation avec cette donnée. Cela peut être une description élémentaire qui vise à objectiver une réalité, le résultat d'une comparaison entre deux événements du même ordre (mesure) soit en d'autres termes une observation ou une mesure. La donnée brute est dépourvue de tout raisonnement, supposition, constatation, probabilité.
OncorhynchusOncorhynchus est un genre de poissons de la famille des salmonidés (saumons, truites et apparentés). La plupart de ces espèces font l'objet d'une pêche commerciale intense, et plusieurs sont considérées comme en danger d'extinction par l'IUCN.

PCR quantitativeLa PCR quantitative (ou qPCR), ou PCR en temps réel, est une méthode particulière de réaction en chaîne par polymérase permettant de mesurer la quantité initiale d'ADN. En réalité, la PCR quantitative mesure le nombre d'amplicon (portion d'ADN définie par un couple d'amorces). Il existe diverses techniques permettant de quantifier l'ADN en biologie moléculaire. On peut utiliser la spectrophotométrie UV-visible à qui permet de connaître avec précision la concentration d'ADN total dans un échantillon par dosage optique.
Biologie cellulairethumb|Détection de filaments d'actine dans des cellules animales (immunofluorescence) La biologie cellulaire (anciennement appelée cytologie) est une discipline scientifique qui étudie les cellules, du point de vue structural et fonctionnel, et les utilise pour des applications en biotechnologie. Elle s'intéresse à l'écosystème cellulaire, c'est-à-dire à l'équilibre dynamique et autorégulé des fonctions cellulaires, dans un contexte normal ou perturbé.
Stem-cell lineA stem cell line is a group of stem cells that is cultured in vitro and can be propagated indefinitely. Stem cell lines are derived from either animal or human tissues and come from one of three sources: embryonic stem cells, adult stem cells, or induced stem cells. They are commonly used in research and regenerative medicine. Stem cell By definition, stem cells possess two properties: (1) they can self-renew, which means that they can divide indefinitely while remaining in an undifferentiated state; and (2) they are pluripotent or multipotent, which means that they can differentiate to form specialized cell types.
Transport proteinA transport protein (variously referred to as a transmembrane pump, transporter, escort protein, acid transport protein, cation transport protein, or anion transport protein) is a protein that serves the function of moving other materials within an organism. Transport proteins are vital to the growth and life of all living things. There are several different kinds of transport proteins. Carrier proteins are proteins involved in the movement of ions, small molecules, or macromolecules, such as another protein, across a biological membrane.
Oncorhynchus clarkiiThe cutthroat trout (Oncorhynchus clarkii) is a fish species of the family Salmonidae native to cold-water tributaries of the Pacific Ocean, Rocky Mountains, and Great Basin in North America. As a member of the genus Oncorhynchus, it is one of the Pacific trout, a group that includes the widely distributed rainbow trout. Cutthroat trout are popular gamefish, especially among anglers who enjoy fly fishing. The common name "cutthroat" refers to the distinctive red coloration on the underside of the lower jaw.
Immortalised cell lineAn immortalised cell line is a population of cells from a multicellular organism which would normally not proliferate indefinitely but, due to mutation, have evaded normal cellular senescence and instead can keep undergoing division. The cells can therefore be grown for prolonged periods in vitro. The mutations required for immortality can occur naturally or be intentionally induced for experimental purposes. Immortal cell lines are a very important tool for research into the biochemistry and cell biology of multicellular organisms.
Immunité cellulaireCell-mediated immunity or cellular immunity is an immune response that does not involve antibodies. Rather, cell-mediated immunity is the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen. In the late 19th century Hippocratic tradition medicine system, the immune system was imagined into two branches: humoral immunity, for which the protective function of immunization could be found in the humor (cell-free bodily fluid or serum) and cellular immunity, for which the protective function of immunization was associated with cells.
Coastal cutthroat troutThe coastal cutthroat trout (Oncorhynchus clarkii clarkii), also known as the sea-run cutthroat trout, blue-back trout or harvest trout, is one of the several subspecies of cutthroat trout found in Western North America. The coastal cutthroat trout occurs in four distinct forms. A semi-anadromous or sea-run form is the most well known. Freshwater forms occur in both large and small rivers and streams and lake environments. The native range of the coastal cutthroat trout extends south from the southern coastline of the Kenai Peninsula in Alaska to the Eel River in Northern California.
