Immunohistochemical analysis of porcine myocardial sections. Representative immunohistochemical staining of porcine myocardial tissue labeled for Collagen-1 (top left), Collagen-3 (top right), α-SMA (bottom left), and vWF (bottom right). Panels correspond to different experimental groups: a–d control, e–h pASC, and i–l coculture. Each section represents a distinct myocardial region: a, e, i remote area, b, f, j right border zone, c, g, k infarct center, and d, h, l left border zone. All images were captured at 100× magnification
