Abstract
The growth factors platelet derived growth factor (PDGF), transforming growth factor alpha (TGF-α) and transforming growth factor beta (TGF-β) have been demonstrated to stimulate the in vitro proliferation of theca and granulosa cells in different animals. The present study was conducted to localise the growth factors PDGF, TGF-α and TGF-β in different types of interstitial cells and stromal cells of normal cycling goat ovaries. Tissue fixed in formalin was processed through a graded series of alcohols and embedded in paraffin wax. The sections were immunohistochemically stained with antibodies against PDGF, TGF-α and TGF-β. The binding affinity of interstitial cells and stromal cells were observed and photographed. The staining pattern of PDGF, TGF-α and TGF-β was mild to strong in stromal cells. The primary and secondary interstitial cells exhibited varied staining patterns for all studied growth factors. These findings in goat suggests that PDGF, TGF-α, TGF-β were potentially an important autocrine regulator of different cell functions and possibly a paracrine regulator of ovarian cell function at various development stages.
