Resumo: 	Abstract In order to investigate the expression levels of nerve growth factor (NGF) and its receptors (TrkA and p75) in prehierarchical follicles and oviducts of hens, five 130-day-old laying hens were examined by immunohistochemistry and RT-PCR analysis. NGF and its receptors were expressed in theca cells and granulosa cells of prehierarchical follicles, and they were also expressed in the epithelial cells of oviducts. The expression of the genes NGF, TrkA and p75 were significantly different in prehierarchical follicles (p&lt;0.05 or p&lt;0.01), and NGF and TrkA gene expression was significantly different in different parts of oviduct (p&lt;0.05 or p&lt;0.01). The expression of NGF and p75 mRNA levels was highest in large white follicle (LWF), as well as the expression of TrkA in small yellow follicle (SYF). In the oviduct, the expression of NGF was the highest in infundibulum, and lowest in isthmus. These results suggest that NGF may play an important role in the regulation of hen reproduction.
