[Apolipoprotein E immunoreactivities in normal human ovary and ovarian neoplasms].
An immunohistochemical study on localization of apoE in normal human ovary and various ovarian neoplasms was performed using polyclonal anti-human apoE antibody. In the normal tissues, apoE immunoreactivity was found in folliculus (theca interna and stratum granulosum), and most intensely in a corpus luteum. The stroma cells were not stained. Among various ovarian tumours, positive staining was found in granulosa cell tumour, teratoma and dysgerminoma. Close relationship between apoE and steroid synthesis was suggested by the distribution of apoE in the studied tissues. The present results show that an immunohistochemical study for apoE may be helpful for the diagnosis of steroid producing tumours.
