endosome

endosome
A more or less central body in the vesicular nucleus of certain Feulgen-negative (DNA-) protozoa ( e.g., trypanosomes, parasitic amebae, and phytoflagellates), with the chromatin (DNA+) lying between the nuclear membrane and the e.. Cf.:nucleolus. [endo- + G. soma, body]

en·do·some 'en-də-.sōm n
1) a conspicuous body other than a chromatin granule that occurs within the nuclear membrane of a vesicular protozoan nucleus and is either a karyosome or a nucleolus
2) a vesicle formed by the invagination and pinching off of the cell membrane during endocytosis

en·do·some (enґdo-sōm) [endo- + -some] 1. in endocytosis, a vesicle that has lost its coat of clathrin. Four classes of endosomes (early, recycling, and late endosomes and multivesicular bodies) are distinguishable; whether they are distinct organelles or functional subsets of a single compartment is uncertain. 2. a nucleolus-like, intranuclear, RNA-containing organelle of certain flagellate protozoa that persists during mitosis.
