Detection of Hypoxia in 2D and 3D Cell Culture Systems Using Genetically Encoded Fluorescent Hypoxia Sensors.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In vivo oxygen availability varies widely between cellular microenvironments, depending on the tissue of origin and its cellular niche. It has long been known that too high or too low oxygen concentrations can act as a biological stressor. Thus, the precise control of oxygen availability should be a consideration for cell culture optimization, especially in the field of three-dimensional (3D) cell culture. In this chapter, we describe a system for visualizing oxygen limitations at a cellular level using human adipose tissue-derived mesenchymal stem cells (hAD-MSCs) that were genetically modified to express a fluorescent hypoxia sensor. This sensor can detect the activation of hypoxia-induced factors (HIF) transcription factors that lead to the expression of the oxygen-independent fluorescent protein, UnaG, at low oxygen concentrations. The response of these hypoxia reporter cells can be evaluated in two-dimensional (2D) and 3D cultivation platforms during exposure to hypoxia (1% O
