Figure 1From: Serum from Patients Undergoing Remote Ischemic Preconditioning Protects Cultured Human Intestinal Cells from Hypoxia-Induced Damage: Involvement of Matrixmetalloproteinase-2 and -9Experimental setting. (A) RIPC protocol in vivo and blood collection. (B) Experimental setting of the in vitro study and morphology of CaCo-2 cells under normoxic conditions and 24 h after a 1-h hypoxia period. Hypoxia leads to cell rounding, detachment from the growth surface and signs of cell damage. Bars denote 100 µm.Back to article page
