Figure 5From: Distinct compartmentalization of SP-A and SP-D in the vasculature and lungs of patients with idiopathic pulmonary fibrosis Immunostaining of blood and lymphatic vessels in lung biopsies from idiopathic pulmonary fibrosis (IPF) patients. (A) The capillary vessels were extremely developed, especially along the air space (red: CD34, brown: SP-A). (B) On the other hand, lymphatic vessels were localized at the center of the stroma (red: D2-40, brown: SP-A).Back to article page
