Fig. 3From: Contralateral artery enlargement predicts carotid plaque progression based on machine learning algorithm models in apoE−/− miceHistopathological and immunohistochemical staining showing plaque composition in apoE−/− and C57BL/6J groups after 28 days. Cross-sections of carotid arteries in different groups were stained for HE, collagen (Masson’s trichrome) and lipids (Oil red O), macrophages (MAC-3) and vascular SMCs (α-actin).
