From: Physiological oxygen tension reduces hepatocyte dedifferentiation in in vitro culture

Physiological oxygen level helps maintain the endothelial phenotype of primary hepatocytes. (A) Morphology of primary hepatocytes cultured in 21% or 5% O2. Scale bar: 50 μM. (B) Immunofluorescence staining of F-actin (red) in primary hepatocytes cultured in 21% or 5% O2. Nuclei were stained with Hoechst. Scale bar: 10 μm.
