Fig. 2From: Rapid and efficient generation of neural progenitors from adult bone marrow stromal cells by hypoxic preconditioningAcute hypoxia triggers upregulation of hypoxia-inducible factor-1 alpha (HIF-1α) and epidermal growth factor receptor (EGFR) in bone marrow stromal cells (BMSCs). Western blots of cell lysates for rat (a) and human BMSCs (b) subjected to hypoxia demonstrated increases in HIF-1α and EGFR protein expression as compared to normoxia controls. c, d Histograms to show densitometric analysis of the indicated protein bands for human BMSCs.
