Transmission electron microscopy (TEM) micrographs of lung surfactant membrane structures and liposome construction of ameba-derived lipids. (A) Lung surfactant membrane structures display mainly as lamellar body (LB) in a premature infant with neonatal respiratory distress syndrome (NRDS). (B) Tubular myelin (TM)-rich surfactant membrane structure from a full-term newborn without NRDS. (C) Liposomal construct using cubic membrane-derived plasmalogen-rich ameba lipids. TEM images of (A,B) are adapted from deMello et al. (1987) with permission. All scale bars = 500 nm.
