Granulosa cells are not easily accessible, unless they are examined in follicular fluid after oocyte retrieval. These samples are usually contaminated with blood. We have set up a general technique for analysis of granulosa cells without physically separating them from blood cells. The sample is stained with CD45, which is a pan-leukocyte marker, and granulosa cells are consecutively selected as CD45 negative during flow cytometric analysis. Analysis of forward scatter of the granulosa cells, which is correlated to cell size, shows a wide size range throughout the whole population rather than two distinct populations as previously suggested.
