Histological images stained with H & E for the 0-day piglet (#2039) that was accidentally killed by the mother sow three days post apex resection surgery. (A) Image of 0-day piglet heart at 2× magnification; (B) Image of 0-day piglet heart at 4× magnification; the yellow arrow is the border zone of the dense cellular population; the red arrow is fibrin zone/fibrin; the blue arrow is necrotic cardiomyocytes; scale bar = 200 μm. (C) Image of 0-day piglet heart at 20× magnification; (D) Image of 0-day piglet heart at 20× magnification; scale bar = 20 μm. (E) Image of 0-day piglet heart at 40× magnification; (F) Image of 0-day piglet heart at 40× magnification; the green arrow is cells with mitotic events; the yellow arrow indicates the cells resembling immature cardiomyocytes; scale bar = 20 μm. H & E: pink–cytoplasm; blue–nuclei; intense red–erythrocytes.
