cultured cell ribonucleic acid level cell line ribonucleic acid level 2023-04-03T17:54:54Z CMO:0003921 This is any measurement of the absolute or relative amount(s) of one or more of the ribonucleic acids (RNAs) found in a specified cell line after in vitro cell culturing for a specified number of passages (harvesting and reseeding/splitting into multiple daughter cultures). A cell linerefers to a defined population of cells that can be maintained in culture for an extended period of time, retaining stability of certain phenotypes and functions. Cell lines are usually clonal, meaning that the entire population originated from a single common ancestor cell. cell line RNA measurement cell line ribonucleic acid composition measurement clinical_measurement_ontology slaulede
