WebAdult granulosa cell tumor. A low-grade malignant, sex cord-stromal tumor with a variable number of fibroblasts and theca cells. A variety of growth patterns occur and are often admixed. Adult granulosa cell tumor accounts for about 1% of all ovarian tumors. WebA granulosa-theca cell co-culture experiment showed that theca cell proliferation can be stimulated and steroid hormone secretion can be increased by the presence of granulosa cells. [9,10] In addition, granulosa cells are involved in the differentiation and acquisition of LH responsiveness in stromal cells of the ovarian cortex. [11]
