AT-like immunoreactivity.

<p><b>A</b>: Panoramic view of a specimen labeled with anti-AT antiserum showing the presence of immunoreactive material in different parts of the body. <b>B</b>: Similar view in which the primary antibody incubation was replaced for saline solution. <b>C</b>: Similar view as in <b>A</b> showing the co-existence of f-actin filaments and immunoreactive material <b>D</b>: A magnified view showing the spatial relationship between AT-like nerve cells and epithelial-muscular cells. Motor nerve cells (green) and epithelial-muscular cells labeled with phalloidin (red).
