Figure 6From: Expression profiling of laser-microdissected intrapulmonary arteries in hypoxia-induced pulmonary hypertensionImmunolocalisation of S100A4. A) S100A4 protein (left panel) co-localises with alpha-smooth muscle actin (right panel). B) Small vessels (marked by arrows) are negative for S100A4 under normoxia (left panel) however stain positive for S100A4 after 21 days of hypoxia.Back to article page
