P.J. Paley and colleagues compared both cancerous and noncancerous ovarian tumors and tissues. The stromal layer of the ovary contains vascular connective tissues in which the follicles are located.
Follicles are structures that hold and support the eggs or ova while they grow.
The growth factor, when detected, was generally expressed within the tumors themselves and not in peripheral tissues, investigators noted. Researchers could find no distinctive patterns that linked the two, but did not rule that possibility out. This information is provided for educational purposes only. Please read the disclaimer .
