<HeLa> is a human <continuous cell line> originating in <cervical cancer> <biological cells> collected from <Henrietta Lacks> in 1951. Its name combines the beginning of her first and last names.<The Legacy of Henrietta Lacks (Johns Hopkins Medicine)>[The Legacy of Henrietta Lacks, opening history and name explanation]{ref}

ATCC's CCL-2 <HeLa> preparation grows attached to a surface. Its product sheet specifies a <cell culture medium> supplemented with <fetal bovine serum>, at $37\,{}^\circ\mathrm{C}$ with $5\%$ <carbon dioxide> in air.<HeLa - CCL-2 by ATCC>[Characteristics, Growth properties; Handling information, Complete medium, Temperature and Atmosphere]{ref} These are specified conditions for that preparation, rather than defining conditions for every <HeLa> derivative.

Continuing access to related <biological cells> makes <HeLa> useful for comparisons of <cell state> and responses to interventions. But a <continuous cell line> is a laboratory model: its history and environment matter, and observations in it do not alone establish responses in an intact <organism>. <Cell counting> measures abundance; a <trypan blue exclusion test> measures a particular membrane-associated readout; neither proves <cell line> identity.
