Albino A. ruthenus, DAPI staining of semithin sections of ovarian nests (A–D) and of individual previtellogenic ovarian follicles (E). Abbreviations: Db, dense bodies; SC, nuclei of somatic cells. (A and B) Nests containing cystoblasts; CBL, cystoblasts; arrowheads, spherical bodies; ch, chromosomes. (A) Empty arrow, chromosomes and fragments of DNA-body during mitotic division in the cystoblast. (B) Empty arrow, chromosomes and fragments of dense body during the anaphase in the cystoblast. (C) CBL, cystoblasts; arrowhead (at the cystoblast), spherical body; ch, chromosome; EZ, early zygotene stage cystocytes; bi, bivalents; arrowhead (at zygotene stage cystocyte), fragment of dense body; asterisk, extrachromosomal DNA. (D) Pachytene stage cystocytes. Asterisk, irregularly shaped DNA-body; arrowhead, fragments of dense body and of spherical bodies; arrow, multiple nucleolus; bi, bivalent. (E) Individual ovarian follicles; no, multiple nucleoli; FC, nuclei in follicular cells; T, nuclei in thecal cells
