Oxygenation in cell culture: Critical parameters for reproducibility are routinely not reported
Open accessAbstract
Mammalian cell culture is foundational to biomedical research, and the reproducibility of research findings across the sciences is drawing increasing attention. While many components contribute to reproducibility, the reporting of factors that impact oxygen delivery in the general biomedical literature has the potential for both significant impact, and immediate improvement. The relationship between the oxygen consumption rate of cells and the diffusive delivery of oxygen through the overlying medium layer means parameters such as medium depth and cell type can cause significant differences in oxygenation for cultures nominally maintained under the same conditions. While oxygenation levels are widely understood to significantly impact the phenotype of cultured cells in the abstract, in practise the importance of the above parameters does not appear to be well recognized in the non-specialist research community. On analyzing two hundred articles from high-impact journals we find a large majority missing at least one key piece of information necessary to ensure consistency in replication. We propose that explicitly reporting these values should be a requirement for publication.

Claims other papers make about this one
Each is checked against this paper’s own text: does it say what the citing paper says it does?
The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“recent assessments show that the majority of research papers rely on nominal set points and fail to directly verify and report environmental parameters (Al-Ani et al., 2018; Michl et al., 2019; Klein et al., 2021b).”
From Toward Best Practices for Controlling Mammalian Cell Culture Environments (2022) · cites this paper as Al-Ani et al., 2018
Experimental — accuracy not yet measuredThe source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“The lack of monitoring and reporting of environmental conditions in cell culture-systems is a pervasive, but under-recognized problem (Hunter, 2017; Al-Ani et al., 2018; Michl et al., 2019; Klein et al., 2021a; Klein et al., 2021b).”

Experimental — accuracy not yet measuredThe source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“Medium changes have been shown to influence oxygen supply and cellular metabolism, as well as synthesis of proteins, DNA, and RNA (Al-Ani et al., 2018; Wright Muelas et al., 2018).”
From In Vitro research Reproducibility: Keeping up High Standards (2019) · cites this paper as Al-Ani et al., 2018
Experimental — accuracy not yet measuredThe cited source says what the claim attributes to it.
In the citing paper
“In addition, the height/level of medium above cells determines the accessibility to oxygen and should be recognized as an important factor for cell culture (Al-Ani et al., 2018).”
From Guidance document on Good cell and tissue culture practice 2.0 (GCCP 2.0) (2021) · cites this paper as Al-Ani et al., 2018
The cited source says what the claim attributes to it.
In the citing paper
“In the case of O2, medium deoxygenation is caused by the disparity between rates of O2 consumption via cellular metabolism and the replenishment of O2 at the air-medium interface (Place et al., 2017; Al-Ani et al., 2018).”
From Toward Best Practices for Controlling Mammalian Cell Culture Environments (2022) · cites this paper as Al-Ani et al., 2018
The check wasn’t confident either way, so it gives no verdict — never disputed.
In the citing paper
“although reliable reports of environmental parameters within selected human tissues are presently limited (Al-Ani et al., 2018; Ast and Mootha, 2019)”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
