Figure 3. Experimental myocardial infarction (MI) and gelatin methacryloyl (GelMA) photo–crosslinking in situ.

Figure 3

A, View of the anterior wall of the left ventricle (LV) through a surgical thoracotomy. Placement of the suture ligation of the anterior interventricular artery is visible. The myocardium distal to the suture is blanched, consistent with ischemic injury. B, View of the anterior wall of the LV through a surgical thoracotomy. Suture ligation of the anterior interventricular artery can be seen as visible light is shone on the anterior LV wall immediately after the GelMA liquid precursor was applied to the area of injury in the anterior wall distal to the suture. C, Representative image of postmortem gross pathological characteristics in animals that did not survive the 3‐week observation period after MI. An anterior view of the thoracic cavity is displayed. Location of the suture ligation on the anterior wall of the heart is visible, as is the region of post‐MI injury. Presence of blood in the chest cavity is visible adjacent to the heart.
