Human collagen type I is present in the infarcted NOD-SCID mouse heart after hEPDC injection. (A) Two days after injection of hEPDCs (green) in the mouse infarcted heart, human collagen I (red) is present. The expression of human collagen I (red) increased at day 4 (B) and 7 (C) after MI. (D). After 6 weeks, hEPDCs (green) were still present in the infarcted mouse heart. At this time point, the total amount of collagen I (white) was prominent, while the amount of human collagen type I (red) was markedly reduced. Images (A'–D') represent location of hEPDCs (green) and human collagen I (red) and images (A”–D”) represent enlargements of images (A'–D'). Scale bar 250 μm.
