Figure 3From: Long term culture of mesenchymal stem cells in hypoxia promotes a genetic program maintaining their undifferentiated and multipotent statusMorphological aspect of MSC. The amount of mitochondria was evaluated by flow cytometry (A) and optical microscopy (B) on MSC stained with Mitotracker Orange. TEM was performed on MSC at P2 culture in normoxic or hypoxic conditions (C). (N = 3)Back to article page
