XY body formation during rat spermatogenesis: an immunocytochemical study using antibodies against XY body-associated proteins.
The process of formation of the XY body during meiotic prophase was investigated by immunocytochemistry on cryosections of pubertal rat testes using antibodies against three different XY body-associated proteins. Here we show that these proteins are detectable at only partially overlapping temporal windows. These findings provide the first evidence that the previously described morphological changes in the structure of the XY body that occur during meiotic prophase are accompanied by considerable changes in its protein composition.
