The expression of mzpc5 in the ovary. Brightfield micrographs of mzpc5 transcripts detected in the ovary of a spawning female medaka using in situ hybridization. Scale bar = 100 µm. The arrows point to mzpc5 expressed in oocytes of varying sizes. Panels a and b show different portions of the same ovary. Only small oocytes (stages I–III) showed intense signals of mzpc5 expression
