is_specified_output_of derives from derives_from cultured cell 培养细胞 A cell in vitro that is or has been maintained or propagated as part of a cell culture. Note that this class was re-labeled to 'cultured cell' instead of 'cell line cell', as it intent was clarified to cover any cultured cells of multicellular and unicellular organisms. This includes cells actively being cultured, or cells that have been cultured but are stored in a quiescent state for future use. In having been cultured, cells must establish homeostasis and often replicate in a foreign environment. Accomodation of this stress initiates a selection of cells fit for such challenges, wherein necessary adaptive biochemical and.or genetic changes can occur. These changes can set them apart from the in vivo cells from which they derive, and such changes will typically accumulate and change over increasing time in culture. cell cultured cell 一种体外细胞，其作为或已被维持或增殖为细胞培养物的一部分。 培养细胞 注意到这一类被重新标记为“培养细胞”而不是“细胞系细胞”，因为其目的被澄清以涵盖多细胞和单细胞生物体的任何培养细胞。这包括活化培养的细胞，或已经培养但以静止状态储存以供将来使用的细胞。在培养过程中，细胞必须建立稳态，并经常在外部环境中复制。这种压力适应启动了适应这种挑战的细胞选择，其中可能发生必要的适应性生化和/或遗传改变。这些变化可以使它们与其来源的体内细胞分开，这种变化通常会随着培养时间的增加而积累和改变。 细胞 experimentally modified cell in vitro 体外实验修饰细胞 cell in vitro 体外细胞 establishing cell culture 建立细胞培养
