Shalaka Sharad Shah,Shilpa ShindeIts effect on immortalization is particularly striking in human cells. Mouse cells have a quite limited life span in culture (approximatelyl0–20 generations) but can spontaneously become immortal at a measurable frequency; infection with wild-type SV40 results in almost 100% occurrence (Tevethia et 作者: inscribe 時(shí)間: 2025-3-23 14:09 作者: 能得到 時(shí)間: 2025-3-23 19:11 作者: Coeval 時(shí)間: 2025-3-24 01:48 作者: parsimony 時(shí)間: 2025-3-24 03:08 作者: MAIZE 時(shí)間: 2025-3-24 07:57
Olympic Games and Global Cities reflect the ability to reproduce indefinitely, since the ancestry of each cell presumably traces back, in an unbroken lineage for over 3 billion years, to the origin of life. As pointed out by Avise (1993), it is not actually cells which are immortal, but cell lineages.作者: 無能性 時(shí)間: 2025-3-24 11:53 作者: exercise 時(shí)間: 2025-3-24 18:46 作者: 聾子 時(shí)間: 2025-3-24 20:16

Olympic Games and Global CitiesSince the early days of tissue culture, the life span of cells has been a mystery: how does the inexorability of death show up in cultured cells? For Alexis Carrel and others, this appeared to be more than a scientific question, as if there was a lesson to be learned about life itself (Witkowsky 1980).作者: 正常 時(shí)間: 2025-3-26 10:38 作者: Optimum 時(shí)間: 2025-3-26 14:23 作者: PACT 時(shí)間: 2025-3-26 19:19 作者: Encephalitis 時(shí)間: 2025-3-26 22:35 作者: Osmosis 時(shí)間: 2025-3-27 01:53 作者: 卵石 時(shí)間: 2025-3-27 08:06
