Bonghan Ducts and Corpuscles with DNA-contained Granules on the Internal Organs-Surfaces of Rabbits

We observed threadlike structure separated partially from peritoneum and connected to the peritoneum or abdominal wall. The corpuscle on the way of the threadlike structure on the organ surface of a rabbit contained 2 µm Size granules. The study with confocal laser scanning microscope revealed that there were DNA inside of the granule. The granule might be a sort of cell-free DNA, or a naturally existing micro-cell.
