Hypoxia enhances proliferation and tissue formation of human mesenchymal stem cells

Abstract

Changes in oxygen concentrations affect many of the innate characteristics of stem and progenitor cells. Human mesenchymal stem cells (hMSCs) were maintained under hypoxic atmospheres (2% O(2)) for up to seven in vitro passages. This resulted in approximately 30-fold higher hMSC expansion over 6 weeks without loss of multi-lineage differentiation capabilities. Under hypoxia, hMSCs maintained their growth-rates even after reaching confluence, resulting in the formation of multiple cell layers. Hypoxic hMSCs also displayed differences in the cell and nuclear morphologies as well as enhanced ECM formation and organization. These changes in cellular characteristics were accompanied by higher mRNA levels of Oct-4 and HIF-2alpha, as well as increased expression levels of connexin-43, a protein used in gap junction formation. The results from this study demonstrated that oxygen concentrations affected many aspects of stem-cell physiology, including growth and in vitro development, and may be a critical parameter during expansion and differentiation.

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.
