idiosomen.

Brit.

/ˈɪdɪəˌsəʊm/, U.S.

/ˈɪdiəˌsoʊm/

Origin: Formed within English, by derivation. Etymons: idio- comb. form, -some comb. form.

Etymology: < idio- comb. form + -some comb. form.In sense 2, originally a mistranscription of German Idiozom (see idiozome n.), but subsequently treated as a variant or replacement term. Compare French idiosome (C. Regaud 1910, in Arch. d'anat. microsc. 11 343).

†1. Biology. Whitman's term for: a hypothetical unit of living protoplasm involved in heredity. Cf. idioblast n. 2, pangene n. Obsolete.

1894 C. O. Whitman in Biol. Lectures 1893 (Wood's Hole, Mass., Marine Biol. Lab.) 123 It will find the secret of organization, growth, development, not in cell-formation, but in those ultimate elements of living matter, for which idiosomes seems to me an appropriate name.

1899 J. A. Thomson Sci. of Life xi. 153 To these hypothetical units numerous names have been given—biophors, pangenes, idiosomes, [etc.].

2. Cell Biology. A distinct spheroidal region of the cytoplasm surrounding the centrioles in the developing germ cells of animals, containing granules and membranous structures and associated with the Golgi apparatus. Also called idiozome.

1899 Science 3 Mar. 319/1 The remains of the centrosphere (idiosome of Meves, mother periplast of Vejdovski) in each blastomere is carried by definite rotations of the protoplasm into one only of the two daughter cells into which the blastomere divides.

1934 L. W. Sharp Introd. Cytol. (ed. 3) xiv. 216 The Golgi bodies are closely aggregated about the centrioles where their lightly staining substance flows together to form the idiosome.

1953 O. E. Nelsen Compar. Embryol. Vertebr. iii. 126 The idiosome (idiozome) is a rounded body of cytoplasm which, in many animal species, takes the cytoplasmic stain more intensely than the surrounding cytoplasm.

1988 Jrnl. Ultrastruct. & Molecular Struct. Res. 98 290/1 At this stage, almost all the mitochondria are precisely organized as a rosette around the idiosome.
