Is it true that human cells can live indefinitely in controlled laboratory environments?

Yes. Multiple studies demonstrate that human and animal cells can be successfully maintained and indefinitely proliferated in controlled laboratory environments through techniques such as hTERT immortalization or viral gene transfer.

Verdict: SUPPORTED · 5 sources for, 0 against · Last checked 4 Aug 2026

The analysis

The claim states that human cells can live indefinitely in controlled laboratory environments, which is a well-established scientific fact through immortalized cell lines and telomerase-mediated expansion. Papers [2] and others directly demonstrate how human and animal cells achieve extended or indefinite proliferation in vitro using hTERT and other immortalization methods. The retrieved evidence consistently supports this biological capability, yielding a verdict of SUPPORTED.
