What Researchers Did
Researchers exposed ten healthy volunteers to hyperbaric air (1.27ATA room air for 90 minutes, 10 times over 2 weeks) to assess its effect on stem progenitor cell mobilization, cytokine expression, and blood counts.
What They Found
Hyperbaric air significantly increased stem progenitor cells (SPCs), showing a 2.5-fold rise after the first exposure and a 7.5-fold increase after nine exposures (p = 0.0001 for both). SPCs remained elevated by 4.5-fold three days post-treatment (p = 0.0001), with increases in IL-6, IL-8, MCP-1, and VEGF, but no changes in complete blood counts.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation of this study is its small sample size of ten healthy volunteers, which may not fully represent diverse patient populations or long-term effects.
