Aggregate Over Tadpole (VIDEO)

University of Pittsburgh

Caption

Green Slime covers the surface of a tadpole (bottom) and a goblet-cell regenerated aggregate (top, not the same scale). The images show the molecule intelectin-1, an important factor in tadpole skin, and one of the slime factors synthesized and secreted by goblet cells (single goblet cells can be seen in the aggregate). In human lung, intelectin-1 binds bacteria and is on the front line of the innate immune system.
