Trophosphere imaging. (A) Scanning electron micrograph of a trophosphere. (B) L-selectin expression was analyzed by confocal microscopy with trophospheres stained with Dreg-56, biotinylated secondary antibody, and Texas Red-conjugated streptavidin (200×). (C, D) Representative light micrographs (100×) of trophospheres used for dimensional analysis. Diameter, circularity, and roundness measurements are (C, 238 μm, 0.77, 0.92) and (D, 299 μm, 0.84, 0.85). Color images available online at www.liebertpub.com/tea
