Implication

Observational study uncovers differential expression of NGF, TrkA, and p75 in fetal and adult ovaries, suggesting distinct roles in follicular assembly and early follicle growth.

Key Points

To investigate the expression of nerve growth factor (NGF) and its receptors, TrkA and p75, during early follicular development in human fetal and adult ovaries.
Evaluated 10 ovarian samples from adolescents and adults aged 13–39 years and 33 fetal ovarian samples aged 19–33 gestational weeks.
Conducted immunocytochemical staining on fixed tissue sections to visualize protein localization of NGF, TrkA, and p75.
Isolated total RNA from frozen ovarian tissue and assessed gene expression using RT-PCR followed by 1% agarose gel electrophoresis.
Immunocytochemical staining detected NGF in granulosa cells and oocytes, TrkA predominantly in oocytes and infrequently in granulosa cells, and p75 in stromal cells only in fetuses younger than 22 gestational weeks.
RT-PCR identified NGF and TrkA mRNA transcripts in all adolescent, adult, and fetal samples, whereas p75 mRNA expression was restricted exclusively to fetal ovaries younger than 22 gestational weeks.
