Fig. 2. Localization profiles of IFITM3 protein.

A: Cytoplasmic spot (black arrowhead) with staining in the plasma membrane (red arrowhead). Cell enlarged from the intraembryonic primitive streak (IPS) of 5-s-staged specimen in Fig. 3B. B: Large cytoplasmic spot (black arrowhead). Cell enlarged from the proximal allantois of 4-s-staged specimen in Fig. 1B2. C: Apical localization (black arrowheads). Cell enlarged from posterior surface ectoderm of 10-s-staged specimen in Fig. 3I. D: Small cytoplasmic spot (black arrowhead). Cell enlarged from the IPS of 4-s staged specimen in Fig. 1B2. Scale bar in A: 5.0 μm (A-D).
