Extracellular matrix (ECM) changes in the carious pulps. d–k Immunostaining analysis of COL1A1 (a–d), LAMININ (e–h), DECORIN (i–l) and Tenascin-C (TNC) (m–p) protein expression (green) in the cryosections of healthy (a, b, e, f, I, j, m, n) and carious (c, d, g, h, k, l, o, p) pulps. DAPI staining (blue) identifies the nuclei. (b, d, f, h, j, l, n, p) are higher magnification images of the areas marked by the white square in a, c, e, g, I, k, m, o. Scale bars represent 100 μm
