Synonyms Hayflick number irreversible replicative senescence mortality stage 1 Definition The term Hayflick limit refers to the fact that the maximum number of cell divisions of a certain cell population is genetically fixed such that aging cells become non-dividing (senescent) at last. This ...
While CSCs can duplicate for an indefinite amount of time, CCs are able to divide only a limited number of times (c.f., Hayflick limit; [23]). A proposed quantitative index for assessing the potential contribution of reprogramming to cancer stem cell kinetics More results ► Encyclopedia bro...
Normal cells proliferate in response to growth signals and can achieve only a defined number of replications often referred to as the Hayflick's limit. When cells are grown in culture, they face two barriers to continuous division; the first being senescence which is an irreversible stage where...

But there is only one eponymous limit in biomedicine: the Hayflick Limit, the number of times (about 50) that normal human embryonic cells can divide before they succumb to senescence. 年份: 2011 收藏 引用 批量引用 报错 分享 全部来源 求助全文 掌桥科研 相似文献...
Cloning is possible when somatic cell differentiation is successfully reprogrammed, and clinical control of cellular senescence depends on a proper reconfiguration of the predetermined number of divisions permitted during the cell life-cycle (the so-called "Hayflick Limit"). In this paper, we discuss ...
In this article the author discusses professor Leonard Hayflick's Hayflick Limit, the number of times that normal human embryonic cells can divide before they succumb to senescence. He states that the professor of the University of California, San Francisco argued that the Hayflick Limit was both ...

Definition Hayflick limit is defined as the specific number of proliferations that a primary human cell can perform in culture. After this limit has been reached, the so‐called replicative or cellular senescence occurs. Ageing Steroid Hormone Receptor Defects, Molecular BasisDefinitionHayflick limit ...
(Effective clonal diversity accounts for both the number and the abundance of T cell clones.) The causes of this observation are incompletely understood. A previous study proposed that it might result from the emergence of certain rare, replication-enhancing mutations in T cells. In this paper, ...
