Figure 1From: Tumour necrosis factor-α production in fibrosing alveolitis is macrophage subset specificHeterogeneity of tumour necrosis factor (TNF)-α secretion by individual mononuclear phagocytes from a patient with systemic sclerosis. Haemolytic plaques obtained after a 12-h culture were assigned to size groupings. Shown are frequency distributions of the percentages of cells with plaques of different areas. AM = alveolar macrophages; Mo = monocytes.Back to article page
