What Researchers Did
The researchers conducted a review to summarize existing literature on oxygen levels in brain tissues, their effects on neural stem cell behavior, and related molecular mechanisms during neurogenesis and cerebral diseases.
What They Found
They found that oxygen concentration is low in foetal brains (0.076-7.6 mmHg) and adult brains (11.4-53.2 mmHg), decreasing during stroke and increasing in hyperbaric environments. Furthermore, moderate hypoxia, specifically 22.8-76 mmHg, was shown to promote the proliferation of neural stem cells and enhance their differentiation into TH-positive neurons.
