Fig. 2. Loss of function of nht arrests mature primary spermatocyte
differentiation and lowers expression of spermatid differentiation genes.
(A,B) Phase-contrast images of whole testes dissected from (A) wild-type and
(B) nht mutant males. Arrows indicate primary spermatocytes;
arrowheads, elongated spermatid bundles in wild-type; the bracket in B shows
the region of dying spermatocytes in nht. (C-H) In situ
hybridization to whole (C,E,G) wild type or (D,F,H)
nhtz-5347/Df(2L)A263 mutant testes with
anti-sense mRNA probes for (C,D) cyclinB, (E,F) fuzzy
onions, (G,H) don juan.
