Characterization of Fluorescent Biofibers from Macerated Hydra

Animals 72 h p.t. were dissociated into a suspension of single cells, fixed and imaged using phase contrast (left column) and fluorescence microscopy (central column). Right column displays the overlay of both images.

(A and B) (A) Picture of a nematocyte containing a green emitting fiber and (B) a group of cells, showing a fiber inside an ectodermal epithelial cell. Nuclei counterstained with DAPI appear in blue in the inset. Scale bars, 10 μm in A, 20 μm in B.

(C) Fluorescence microscopy of fibers present into the macerated solution. Several structures are formed, presenting both linear and bent motifs, of average length higher than biofibers.
