Figure 2From: Altered surfactant homeostasis and recurrent respiratory failure secondary to TTF-1 nuclear targeting defectAlveolar type II cell ultrastructure. Transmission electron microscopy of lung tissue. A. normal lung tissue of a 5 month-old infant obtained from lobectomy for congenital cystic adenoid malformation showing a type II cell with numerous lamellar bodies filled with concentric pseudomyelin membranes, magnification 3000 ×. B. Detail of one lamellar body, 8000 ×. C. lung tissue form the patient's biopsy, showing a type II cell with smaller, denser lamellar bodies. D. Detail of one lamellar body with poorly structured content, Magnification bar: 1 μm.Back to article page
