In the second form of atresia, only the oocyte is released into the ovarian lumen, leaving behind the
granulosa and empty follicular envelops.

Bilateral aggressive malignant
granulosa cell tumour with essentially different immunophenotypes in primary and metastatic lesions comprising predominantly sarcomatoid and fibrothecomatous patterns-looking for prognostic markers: A case report.
The differential diagnosis of cellular fibroma versus adult
granulosa cell tumor may be problematic, as some
granulosa cell tumors have a diffuse growth of cells that are somewhat spindled (so-called sarcomatoid
granulosa cell tumor), and only focal hints of epithelial differentiation may be a subtle clue to the diagnosis.
Sin embargo, en el avestruz los foliculos en diferentes estados de desarrollo muestran miofibroblastos de disposicion concentrica (teca) que rodean la capa
granulosa. Los miofibroblastos son muy notorios en la envoltura tecal de los foliculos vitelogenicos.

N.P., Ritvos, O., Bone morphogenetic protein 15 and growth differentiation factor 9 cooperate to regulate
granulosa cell function in ruminants.
It was important to understand if this herb affected the oocytes or their supporting
granulosa cells that are critical for reproduction.
The developmental stages of follicles have been defined previously (2) as: i) primordial (one layer of flattened
granulosa cells around the oocyte); ii) transitional (one layer of flattened to cuboidal
granulosa cells around the oocyte); iii) primary (a single layer of cuboidal
granulosa cells); iv) secondary (two or more layers of cuboidal
granulosa cells).
Granulosa cells produce antioxidants to protect oocytes from the detrimental effects of excessive ROS (6).
The different types of sex cord stromal tumours include fibromathecoma,
granulosa cell tumour (adult and juvenile, which differentiates into female characteristics), Sertoli-Leydig cell tumour (which differentiates into male characteristics).
