Fig. 1. Lymphangiogenesis in fibrous stroma in tumor with high elasticity value and low elasticity value. In tumor with high elasticity value (case 19, mean elasticity value: 230.0 kPa) shows lymphatic spaces (maximal microlymphatic density: 23.0) embedded in fibrotic tumor stroma (A), which are highlighted by D2-40 immunohistochemical staining (B). In tumor with low elasticity value (case 116, mean elasticity value: 56.5 kPa), lymphatic space is rarely found in fibrotic area (C) by D2-40 staining (D) (arrowheads).
