Figure 1From: Medaka villin 1-like protein (VILL) is associated with the formation of microvilli induced by decreasing salinities in the absorptive ionocytesThe ultrastructures of microvilli were observed (50,000×) in the apical regions of FW-type ionocytes under scanning electronic microscope (SEM; A) and under transmission electronic microscope (TEM; B). The cell cortex (Co) with numerous cytoskeletal filaments was identified by its different electron density (white dotted line) in the cell cortex. The microvilli (arrowheads) containing cytoskeletal filaments extended from the cell membrane (asterisks). The arrows indicated the tubular system in the cytoplasm of the ionocyte.
