Figure 4From: Low physiologic oxygen tensions reduce proliferation and differentiation of human multipotent mesenchymal stromal cellsFlow cytometric cell cycle analysis of MSC under atmospheric and reduced oxygen conditions. Cells were permeabilized and stained with propidium iodide. DNA content-related cell cycle distribution of MSC after 7 days of incubation under 21% O2 and 1% O2 (n = 3).Back to article page
