Limitations of oxygen delivery to cells in culture: An underappreciated problem in basic and translational research
Open accessAbstract
Molecular oxygen is one of the most important variables in modern cell culture systems. Fluctuations in its concentration can affect cell growth, differentiation, signaling, and free radical production. In order to maintain culture viability, experimental validity, and reproducibility, it is imperative that oxygen levels be consistently maintained within physiological "normoxic" limits. Use of the term normoxia, however, is not consistent among scientists who experiment in cell culture. It is typically used to describe the atmospheric conditions of a standard incubator, not the true microenvironment to which the cells are exposed. This error may lead to the situation where cells grown in a standard "normoxic" oxygen concentration may actually be experiencing a wide range of conditions ranging from hyperoxia to near-anoxic conditions at the cellular level. This apparent paradox is created by oxygen's sluggish rate of diffusion through aqueous medium, and the generally underappreciated effects that cell density, media volume, and barometric pressure can have on pericellular oxygen concentration in a cell culture system. This review aims to provide an overview of this phenomenon we have termed "consumptive oxygen depletion" (COD), and includes a basic review of the physics, potential consequences, and alternative culture methods currently available to help circumvent this largely unrecognized problem.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
The cited source says what the claim attributes to it.
In the citing paper
“Specifically, O2 first dissolves at the air-medium interface and then diffuses through the liquid (at least several millimeters) to reach and oxygenate cell microenvironments (Place et al., 2017) even as cells undergo exponential growth.”

The cited source says what the claim attributes to it.
In the citing paper
“In concert, these processes interact to create a changing environmental gradient from the surface of the medium down to the microenvironment of the cells (Place et al., 2017).”

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).”

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.
