[Ultrastructure and significance of the "tubular bodies" and "particles" of the hydra mesoglia].

Previous investigations described two kinds of enigmatic ultrastructures in Hydra mesogloea, "tubular bodies" and "particles". Evidence is presented that "tubular bodies" are cytoplasmic spiral processes, 1 500 A thick, often containing polysaccharidic particles (900 A in diameter). Large extracellular "particles" (450-800 A) are also identified as polysaccharides. These particles are enclosed in a meshwork of closely arranged fibrils. The relationship of the "tubular bodies" to polysaccharidic extracellular particles is discussed.
